Bonanza Bros, Blast Corps, Kingdom Hearts 358/2 Days, Vampire: The Masquerade -Bloodlines, Cruisn World, LEGO Battles, NBA Jam
Bonanza Bros would be a great couch co-op multiplayer game in a world where we need more. It would benefit from some gameplay tweaks, and adding online play and 4 players would be big.
Blast Corps was awesome, I found it to be an extremely underrated Rare game. This game in an engine with simulated rubble and crazy explosions would be a gem. I also think changing the camera to first person should be an option at the very least.
Kingdom Hearts 358/2 Days got its cutscenes remastered. I want the full game. It was dripping in atmosphere, and I loved the premise of scouting the new worlds. The graphics could use an upgrade, and the combat could be brought up to par with KH2. But, I love the leveling system and think it would barely need touching.
Vampire: The Masquerade - Bloodlines is awesome and not super long. It's extremely buggy, but luckily there's a modder named Wesp5 who has spend YEARS creating an Unofficial Patch, to a point where all the cut content is restored and it's essentially feature-complete. There's a version that just patches the game, and a restored content version. I think he should be given a team and be allowed to curate content and rebalance cut mechanics for a remake. It would be magical.
Cruisn World is one of my favorite arcade racers ever. It has untouchable vibes, and I'd just like to see that with a nice sheen over it, maybe more levels and vehicles?
LEGO Battles is an RTS for the Nintendo DS. Put it on PC, nuff said.
NBA Jam is not very niche. I want a remake, and I don't care if it's up-to-date. It's the best sports game period.
