Yeah man 1 and 2 are great games, but 4, 5, and 6, while good games they had a tendency to get stale with the same type game engine, if you've played one mega man game on the NES you've played them all. Granted there where some cool additions too the series with those games i.e. The Mega Buster, The Jet Pack....Even with that being said I'd still recommend playing them all..
