So here is a list of all the games I want for each system. Once I finish this, i'll probably be done with collecting. This list contains what I feel are the definitive/good games for each system, as well as some games thrown in for nostalgia reasons. I want to know if I am missing anything that might be a hidden gem.
When it comes to the PS2/Gamecube/Xbox/Dreamcast era, I only focus on exclusives, with anything that is multiplatform going to the Xbox. Also, the Xbox list doesn't contain what I already own, so games like KOTOR, Halo, etc I already own, but aren't on this list. The prices next to the games are the general ebay completed listing price. I have this list on my phone when i go game hunting, so that I know if i'm getting a good deal or not. Games that do not have a price next to them are games I already own (some exceptions with recent purchases not being updated) The NES list hasn't been priced out yet.
