What I mainly mean with this thread topic are the games that you hear about and you get excited about and then they come out and for whatever reason you never get them or play them and time keeps passing and eventually you either lose interest or the games are no longer sold and become impossible to find. So which games fit that criteria for you?
For me, these are a few examples:
1) Civ 4. I wanted to get this game since I first heard it was in development, but to this day I still don't have a PC which can meet the minimum system requirements. Why in God's name did they make this game in 3D?!
2) Pikmin 1 & 2 for the Gamecube. I heard great things about both and I actually picked up a used copy of Pikmin 1 for very cheap so I actually own this one, but I've never got around to playing it for some reason.
3) Lord of the Rings: The Return of the King. I have the Two Towers and I loved that, so I thought I would get the ROTK when it came out, but I never did for some unknown reason.
4) Paper Mario. It is Mario in an RPG and I love both Mario and RPGs so why have I still not played this?
5) Pokemon. It has been around for a decade now and is still insanely popular, yet I've never played any of it.
6) Smash Bros. Brawl for the Wii. I do not have this yet, but I would like to and perhaps some day I will.
7) Syberia 2 for the PC. I played Syberia 1 and loved it and I own Syberia 2, but I just never got around to playing it.
Metroid for the NES. I am a huge fan of the Metroid games, but my first experience with the series was with Super Metroid for the SNES. I regreat that I have never been able to play the original.
9) Earthworm Jim. This game looked awesome back in the mid-90s when it came out. I've never played it, though.
10) Boogerman. Same as above.
There are many others as well, but I think I will stop with these 10 because I could probably go on forever with this. What about you guys? Just some highlights will be fine, because I realize the lists could end up very long if we tried to be comprehensive about it.
