SHINOBI: Art of Vengeance is out now! I had the chance to contribute a few tracks, and Tee Lopes absolutely crushed it with an incredible soundtrack. Big love to the SEGA team for making this happen. Hope you all have as much fun playing it as we did making it!

We’re planning to release an Earthion update soon, which will fix bugs such as ranking display errors (enemy defeat count) and issues related to achievements. We’re sorry, but this will require a one-time reset of the rankings.

Here’s a video excerpt from Earthion Stage 3, recently revealed and captured directly from my Mega Drive. Watch as huge set pieces slam and shift in real time, with sound effects that hit like never before. And wait until you see the massive boss.

From Streets of Rage to Earthion 34 years ago I composed the soundtrack for a game that became part of Mega Drive history. Now, I’m back with a brand-new shooter packed with even more energy, speed, and power. Earthion lands on July 31. The countdown has begun. youtu.be/q-PEQZNurFs?...

Remember those hand-drawn shmup posters on arcade walls in the late ’80s? We asked legendary illustrator Mitsuhiro Arita, known for the Pokémon TCG, to bring that spirit into Earthion’s key visual. It’s our tribute to the golden age of arcade shooters.

I tried uploading a 2:57 video, but unfortunately, I ran into an error. It looks like it’ll take some more time to fix this issue.

Is the video length on Bluesky still capped at 1 minute? Hope they extend it! I’d love to share more videos that fans are into.

Thank you @bsky.app for the warm welcome and for considering our needs. My Japanese followers are really enjoying the spam-free experience on Bluesky. It would be fantastic if you could introduce a feature for direct video media sharing.

The new M! Games issue is out with some great articles! I there´s a nice special about the works and career of the wonderful @yuzokoshiro.bsky.social and I dug deep into the also amazing EGGCONSOLE. Absolutely fascinating stuff. And there's more!

First of all, you should take the initial step; when starting something challenging and new, don't succumb to normalcy bias.

I really love music with catchy melodies, awesome chord progressions, and beats that pump you up. It would also be great if it's unique! キャッチーなメロとクールなコード進行とノリノリなビートの音楽が好き。個性的であれば尚良し！

Seriously, is there no bot here on Bluesky or what? I'm amazed how the followers just keep going up more than I expected, guessing Bluesky is really getting noticed. ここほんとにボットいないのかなぁ。フォロワー増えすぎな気もするけどblueskyの認知度上がってるのかな

I believe that when your hard work doesn't pay off and you feel low, it will be a great opportunity for growth. Life is always about learning.

Out of habit I keep posting serious comments… as followers here are gradually increasing. Though I posted a silly drinking comment on X just now.😆 フォロワー増えてきたらやっぱりコメが硬くなっちゃうなー

Does selling domains seem part of their business? That ‘xyz’ domain has a cool, City Hunter vibe to it. 😁 ドメイン販売も収入の一環なんかな？xyzはシティーハンター味あって良いね👍

I'm curious how Bluesky keeps things running without ads. Feels like it's gonna get tough with more users coming in. I really like it here, though. But you know what they say, 'If it sounds too good to be true, it probably is.' ブルスカ、広告もなくどうやって運営維持してるか謎ですよね。ユーザー増え続けたら大変そうだけど、タダほど怖いものはないって言うしな…🤔

After turning 55, I've increasingly felt the proximity of life's end more than ever with each passing day. Now in mid-February, I'm reminded of how quickly time flies. I have determined to cherish each day of my journey. 今年ももう2月半ば。早いですね。55歳以降、最近は人生の終着駅をより意識するようになりました。1日1日を大切に過ごしていきたいです。

I always wonder why they don't make the most of AI in eliminating spam bots, even though they've invested tons of money in developing and researching it. 常々思っていますが、なんでAIをボット排除に使わないんだろう。かなり投資して研究開発していると思うのですが。

I'll share some silly stuff here but steer clear of the gloomy stuff that could bring my followers down. Even though it could be different how you feel reading it. どうでも良いくだらない事は書きますが、不快に感じるようなポストはしないようにしたいですね。感じ方は人それぞれではありますが…

Not seeing bad news or content that makes you feel disgusted in your feed isn't always a plus, but I’ve found that my heart stays calm in this quieter space.😙 バッドニュースや気分の悪くなるポストが見えないのは必ずしも良いとは言えないけどここは落ち着きますね〜

What do you call those spammers who post tons of replies just to rack up impression money on X? In Japan, we call them 'impression zombies'. Anyway, I’m just glad we don’t have to deal with any clickbait spammers here, saving us the bother of sending numerous reports and blocking them.😙

Should I really have to create a dedicated YouTube channel just for posting music videos on Bluesky? That seems bothersome and like a waste of time. We need a video posting system even here. ここに音楽の動画投稿するために専用のyoutubeチャンネル作るのもなんか面倒だしなぁ…やっぱり動画投稿できるといいですよね
