Traveller is the greatest of sci-fi RPGs. It has maintained its enduring legacy for almost 50 years. Elite, EVE Online, and Starfield were influenced by Traveller.

Just saying: Skyrealms of Jorune was doing a surprising amount of Avatar decades earlier. Floating islands. Human colonists with advanced technology. Indigenous peoples tied to an alien world humans barely understand. Ecological weirdness. Pandora: we’ve seen some of this sky before. 🌙 #ttrpg

Classic Traveller isn’t OSR. It’s one of the original Old School games from which we can recognise an OSR style. Classic Traveller arguably demonstrates that many things subsequently identified as “OSR principles” weren’t really D&D principles. They were 1970s #ttrpg design principles.

I’m a big fan of Jorune. Jorune came to be through the talents of Andrew and Amy Leker and the pencil of Miles Tevez. I was in the joruni facebook group and it’s all grey-hairs. That made me sad because at some point these old grey-haired men will die and that will be the end of it. Jorune dies.

Supergirl (2026) mini review: 9/10 I really enjoyed this. The actress embodied a lot of range and it really felt like a coming-of-age story. It loses 1/2 point because I think while Superman holds back, Supergirl had no reason to. It loses the other 1/2 point for Lobo. I don’t like edgelords.

Time Killers isn’t about killing people. Not really. It’s about history. Making people aware of who historical figures were and the impact they could have had on the timeline. MLK, Karen Silkwood, Marilyn Monroe, Emily Wilding Davison. Also Jeffrey Epstein didn’t commit suicide.
