So I bought 23 new console games

DS (8 games) :

Rune Factory: A Fantasy Harvest Moon (Jan, import), The World Ends With You (May), Etrian Odyssey (Jun), Izuna (Jun), Apollo Justice: Ace Attorney (Aug), Children of Mana (Aug, 10 euros), Sonic Chronicles: The Dark Brotherhood (Sep), Harvest Moon: Island of Hapiness (Dec)

All finished, except Harvest Moon: IoH, that I'm currently playing.

Rune Factory, The World Ends With You (to my greatest surprise), Etrian Odyssey, Izuna, Apollo Justice and Harvest Moon: IoH (so far) excellent.

Children of Mana was very boring (but thankfully, I only payed it 10 euros), and Sonic Chronicles quite disappointing (should have saved the money for Castlevania: Order of Ecclesia or Professor Layton).

PC (1 game) :

Spore (Oct)

Spore didn't lived up to my expectation. A lot of potential, but the developpers have probably been too much ambitious. Maybe the extensions will improve that...

So 9 games bought in total (~360 euros). Finished 8. Not bad considering how much work I have had this year, and that video-game isn't my main leisure (I spend ~150-200 euros per month on mangas, anime, J-Music and derivated just to give an idea).

I won't put dates out since I've forgotten, but one important note - I didn't own a current gen console until 2008. Yeah, all of my games were bought 08... I nearly forgot this fact.

22 retail games total, sold 3 of them. 7 downloadable games bought. Any games on my profile that don't show up here (like all DS games) I just borrowed and played from friends/family.

Wow. Spent quite a lot for games this year (the hardware in particular, systems and controllers). Most of the games I buy aren't at full retail price (often far from it), I'm way too cheap for that...

edit: I don't know what the hell I was thinking. Forgot we had a PS3 for a long time now... but nobody really used it until CoD4 (bought 08). Also, I haven't finished a ton of these games - my priority ends up playing the games I borrow from others (they're often more desirable), since the games I own aren't going anywhere. Now I have a massive back catalogue of games, yet I still want new ones. I guess that's a good thing, better than bitching about no games being out...
