iNinja is one of the most interesting games from Namco. I think it's warp room layout and gameplay style would've been suited for the Crash Bandicoot universe.
Older games feel either more challenging, or well put together.
Spongebob for Gamecube also resembles Crash.
Is it me, or do games where a few hits result in a loss have more nostalgia and fun than games with large health bars.
