Advanced Adventure was good. It's a high quality side-scrolling beat em up for sure. The moves you can do are quite varied, there are different level types (such as one-on-one battles and flying the Nimbus. The battle against Yamcha was ridiculously difficult lol, his Wolf Fang Fist is pretty much broken) and it has high replayability since there are different difficulties, you can play as Krillin after you beat the game and there are new collectable item areas unlocked in the levels and the second playthrough would feel different, just because by then you'll be good at the game and know the controls properly.
It had good mainstream reviews.
Attack of the Saiyans is a really good RPG too, if you've never played that. If you talk to the non-playable characters at every stage of the game across the whole map, you'll find they really fleshed out the script because they always have new things to say. There's a dog inside Capsule Corp that says some pretty profound philosophical stuff and a cat worrying about a paedo pervert in the park in West City.
