May be a little off from what you're asking but one of my favorite games period is Bookworm on the GBA. It was originally a flash game but when it came to GBA you could save your progress. The music was so cute and the sound effects were just awesome. They tried to bring it to the DS without that music and the effects and it just didn't work. Other iterations exist as well, none as cool and enjoyable as the GBA version. I'm stuck emulating until someone rediscovers this neat little game and brings it to switch or steamdeck.

Just for your information, there are actually two other games related to Rocket Slime. Unfortunately they are JP only. The one that release outside of Japan is the 2nd game. There's a GBA game that came out before it and a sequel to the DS game focused on pirate ships

Kenka Bancho. It's a series of japanese games for the PSP, with only the 3rd game being officially translated and released outside Japan as Kenka Bancho Badass Rumble. It's like playing a typical shonen anime set in high school, you're a delinquent who fights everyone from the other schools in order to become the ultimate badass. It's semi open world and you can beat pedestrians and innocent civilians, which reduce your badass meter, because real badasses only fight people who can fight back! And with their bare hands, weapons are for weak pussies! It's over the top and fun as hell. I've only ever met one other person mention that game, and it was an RPG friend of mine, when he bought a PSP for himself.

Something I highly recommend for anyone that enjoyed River City Ransom or similar beat'em ups.

Puppeteer for ps3. It was creative and underrated

Chrono triggiger

Serious Sam

X-beyond the frontier got me into space games as a kid. Had trading, piracy, fighting, ship building, factory ownership. Great series, and they made more after that. I've never met a single person that has played that game before.

Digital Devil Saga on PS2. It's a favorite, easily outshines other SMT games in narrative, character development, and plot twists.

Yet I bring it up at a wedding reception and I'm the weirdo. Pfft.

There used to be a game I found when shareware was still a thing. It was called Harry the Handsome Executive. You basically scoot around on a chair in an office throwing pencils and avoiding traps, it was cute

Monday Night Combat/Super Monday Night Combat. Absolutely loved that game, and a lot of the FPS I play is to fill that hole

I miss the savage series. Probably no chance of those coming back though.
