This is something I've been thinking of for a while, what actually makes games "good"? I understand this is a topic which is based highly on opinions rather than hard facts, so consider it an open-ended question. Personally, I believe replayability is a large factor in rating a game as good. I know some of my favourite games had a high degree of replayability (Mario 64, Super Smash Bros Melee, F-Zero GX, Resident Evil remake). What do you guys think?
