I bought 30+ more games this year for PC/PS3/PSN/Wii/WiiWare/DS/PSP (and got 4 PC games from my Steam Secret Santa).

Ridiculous.

2009 is over in 5 minutes and I just skipped my initial New Year's resolution.
My new plan for 2010 is to play all games I bought in 2009 and to buy not more than 10 new games across all platforms within the next year.

Happy New Year everyone!

It's actually quite easy and quick to buy games nowadays

Wow I'm amazed how many games some folks are capable of buying/playing. Wish I had the time. I've only bought these, haven't completed any of them either :(

Yep I did my part for the gaming industry this year

You dirty cheater

wtf, do you guys have jobs or anything?

I play about 5+ hours a day and I'm having trouble finishing 20-30 games in a year.
For example, I'm just about to finally platinum gundam 2 dynasty warriors, after roughly 160 hours. I'm working on etrian odyssey (40 hours in), Uncharted 2 (80 hours of game time)

That right there is two months worth of gaming.....
On top of it, I haven't even touched COD2 story mode yet, I'm getting Bayonetta in 5 days, have a 2-games-out gamefly subscription of which I haven't even started the game I got 2 days ago....

My definition of "finishing a game" is when I complete the singleplayer mode and not when I get my platinum trophy or 1000G.
