After working the past few weeks kinda nonstop at my job, I'm back and this time with some nice games to add to the collection!
I went to Gamestop's buy 2 get 1 free sale, and found some sweet finds:
Advance Wars: Days of Ruin, DS, Used, Complete, $8
Shining Force Neo, PS2, Used, Complete, Free
Bloody Roar 3, PS2, Used, Complete, $7
Bulletstorm (Limited Edition Cover), PS3, Used, Complete, $17
Sonic & Sega All-Stars Racing, PS3, Used, Complete, $18
Silent Hill 2 (GH Version, This has all the extra content that the Original did not, that the Xbox Version saw), PS2, Used, Complete, Free (Also came with a copy of Silent Hill 3's Soundtrack... previous owner must have forgotten to take it out.)
Also, finally got Ace Attorney Miles Edgeworth Investigations, DS, New, $30 (I've been putting it off for 3 years, I have to get this game now before it's too late.)
Anyway, my best advice when it comes to buy 2 get 1 free sales, Is go for the odlewr games. Especially since, they are often cheaper, and if you don't have the time to play a game now, you won't waste your dollars as if you were buing 2 $50/$40 used games).
