Biggest omission that springs to mind is probably Cybernator. Great game.
For example, I remember there being a bunch of Kirby games, but not how each one was separately named.
Super Metroid is always overrated. Top 10? Sure. But somewhere between 8-10 and absolutely behind DKC 2, Super Mario World, Final Fantasy III (VI), and more.
It does sadden me playing it though to realise how many great games Europe missed out on at the time though.
