Thanks for hosting #TurnBasedThursday! This week, I've done a write up of the crafting system for Revenge of the Firstborn. It's a very accurate implementation of the 3.5 SRD's crafting system. You check out the writeup at tinyurl.com/4xuwr6xh

There might be some who say that Baldur’s Gate 3 brought back the isometric RPG, but here at TBL, we know that the classic genre never went anywhere. Here are 20 of the most promising that are actually in development. turnbasedlovers.com/lists/20-pro... #turnbased #crpg #indiegames

Hired a few voice actors to do those "what do you need" and "I'm on my way" barks you hear when you have a character do something in an isometric RPG. Was surprisingly economical using r/Voicework. And results have been really good.

Hopefully you’ve found this little peek under the hood of the engine interesting. Keep an eye out for more details in future updates!

Rob Koska @rob-in-mn.bsky.social · 20/04/2025

Similarly, grappling is more likely if the agent is clearly stronger (a very large difference in strength score) and if the target is a spellcaster who would be largely neutralized by being unable to freely move their limbs.

100

Rob Koska @rob-in-mn.bsky.social · 20/04/2025

The game uses a similar scoring system for what type of an attack an agent should make. For instance, a trip attack gets a higher score if the agent is bigger than its target and it has the Improved Trip feat.

100

Rob Koska @rob-in-mn.bsky.social · 20/04/2025

For instance, average intelligence creatures are smart enough to attempt to flank you in combat, but non-intelligent ones are not. Creatures can also add new actions to the baseline collection. For example, the medusa has an addition action for using its petrifying gaze attack.

100

Rob Koska @rob-in-mn.bsky.social · 20/04/2025

The game has several baseline utility action collections – it has one for average intelligence agents, non-intelligent agents (undead) and even a few specific ones such as dragons. This helps give agents different behaviors as appropriate.

100

Rob Koska @rob-in-mn.bsky.social · 20/04/2025

So, we are left with the following utility scores: • Use Healing Potion – 25 • Attack Enemy – 10 • Run Away in Fear – 75 Making the clear winner Run Away in Fear. The actor will attempt to find a place that is far away from the source of its fear and run to that location.

100

Rob Koska @rob-in-mn.bsky.social · 20/04/2025

However, the ai actor has a fear effect. The fear effect has a very high utility score because fear supersedes any other actions the agent could take. The Run Away in Fear action has a score of 75.

100

Rob Koska @rob-in-mn.bsky.social · 20/04/2025

Let’s say that our hypothetical agent has a potion, is low on health and is not in danger. This would make our Use Potion utility have a final score of 25. We don’t have any enemies close by, so the attack utility is low, perhaps 10.

100

Rob Koska @rob-in-mn.bsky.social · 20/04/2025

Lastly, is the agent close enough to an enemy that the enemy can make an attack of opportunity on them if they drink a potion? If so, we reduce the score by 10. This would make the action’s final score 15, meaning it is less likely to be chosen, but not impossible to be chosen.

100

Rob Koska @rob-in-mn.bsky.social · 20/04/2025

The next step is evaluating the NPC’s health. If they are at full health, this check adds nothing to the score, however if they are below, say, 50% we increase the score so the final score for this utility is higher than the baseline of 0. Let’s say this action increase the utility score to 25.

100

Rob Koska @rob-in-mn.bsky.social · 20/04/2025

Does the agent have an AI potion in its inventory? If not, we assign a very negative value for the score of this decision input to ensure that no other "true" scores can raise it above 0, which is the default.

100

Rob Koska @rob-in-mn.bsky.social · 20/04/2025

Let’s take an example of drinking a healing potion. To get the healing potion utility score, the game has several inputs that can raise or lower the final score. They are:

100

Rob Koska @rob-in-mn.bsky.social · 20/04/2025

I thought I’d change things up a bit and talk about one of the backend systems in Revenge of the Firstborn, the AI system. utility AI, each action that an agent can take is given a “utility” score where utility refers to how happy the actor would be if it took the given action.

Thanks for hosting #turnbasedthursday! Revenge of the Firstborn is a classic, isometric RPG. It's based on the D&D 3.5 rules for more crunchy combat and character building than the current edition.

Rob Koska @rob-in-mn.bsky.social · 30/03/2025

In Revenge of the Firstborn, armor class is specific to damage types, so full plate protects better against slashing damage than bludgeoning and leather armor protects better against bludgeoning than piercing. This is one of several optional rules in the game. #screenshotsaturday

In addition to a full, hand-crafted campaign, Revenge of the Firstborn has a roguelike mode called the "Endless Dungeon" complete with randomly generated layouts, loot and monsters. In addition, small quests to challenge you are sprinkled throughout the dungeon to up the ante. #screenshotsaturday

Pretty cool development for Revenge of the Firstborn this week. Zappastuff, the modder behind the unfinished business mod for Solasta reached out to me about modding my game. He's got early access to the game now and I can't wait to see what he creates to expand the experience!

Yeah, it's an underrated classic. They were done dirty by their publisher and so the game was launch in a pretty rough state.

120

Rob Koska @rob-in-mn.bsky.social · 21/02/2025

Well I've been working on the game since a little before Solasta was public, so it's probably more accurate to say we have similar inspiration. The most direct inspiration would be (patched) Temple of Elemental Evil. I've taken what I love from it and added some of the things that I missed in it.
