FFX - PS2

I didn't even put it in the console once, I want to finish FFXII first but I'm stuck at a boss and I'm too lazy to level up.

Syphon Filter 3 - PS1

same as above, never played it

Genji : Days of the Blade - PS3

Played it for some time, was ok, I'll continue it one day.

Okami - PS2

Played it but rented it, I still have the saves so I will buy it one day.

I guess I have some...

GC:

- Baten Kaitos Origins: I'm playing Eternal Wings first
- Rogue Leader: played some missions but stopped in the gas one because of the frustration caused by game overs and a f***ing weak ship

PC, a lot now:

I bought the id Collection last year, and since then I haven't touched:

- The Quake series
- Doom series (I'm in the middle of Doom 1)
- Return to Castle Wolfenstein, Spearhead
- Heretic
- Hexen 2 (played a bit of Hexen though)

- Opposing Force and Blue Shift and didn't even install them

- Didn't play Hitman and Hitman 2
- Haven't installed Penumbra Black Plague and Requiem
- Dreamfall: also never played
- Assassin's Creed: just bought it, didn't install it
- Giants: Citizen Kabuto: I have it for years now but installed once and barely played it
- Messiah: same as above
- MDK2: played until the first boss, then I stopped

and then there are some that I simply stopped playing after quite some time: STALKER, Four Swords Adventures, The Longest Journey, Bionic Commando Rearmed

Motorstorm.

Excellent racing game but once you get some new games, you won't play it for a while. But I would get Motorstorm Pacific Drift though

Shame. On. You.

I have the problem that I don't have convenient access to my game systems so I buy games and then promptly forget about them.

@twesterm
I can really understand you, that you stopped playing Lost Odyssey after a short while. I did the same, because the 2nd boss was a damn bitch and I was too lazy at that moment to grind my characters to insane high levels. Well after 10 or more months a friend convinced me to play it again. After 5 hours of grinding I finally beat that assfuck and continued the game. You really need to keep playing it. It's worth it !

OT:
PC
Baldur's Gate 2 - Never came around to finish it :(
Far Cry - Awesome game to check you PC power a few years ago. Only played the first 2 levels ^^
Half-Life - about half through (lol "half" - got it ? Yeah it wasn't that funny.....)
XIII - I'm stuck on the last level

PS3
Uncharted - Stuck on chapter 4 or 5. Too many enemies and I would prefer the cover/shooting style of Gears.
Gran Turismo 5 Prologue - About 6 races left, but I want that damn Ferrari F2007 !!!!
Ratchet & Clank TOD - 3 levels played. I always need a bit longer for platformers

360
Including my brother's games and considering all the missing achievements..... too much !!!

The outfit (360) got distracted by falllout 3..

Shadow of rome (ps2) Have the last couple parts left... Frusterating team AI....

Combat mission: shock force (pc) paradoxpublished it, got it cheap, and it looks good, so...
