My most recent major purchase is the newest Blazblue game, Chronophantasma, which I'd been waiting for for ages.
And it sure does not disappoint. Seven new characters, additional moves for the already-existing cast, redrawn, nicer sprites, and some big mechanic changes as well. Bloody amazing so far.
This is the Japanese version though of course. The English version doesnt come out until March here in the States, and I'm not patient enough to wait. Not sure if it comes out at that time in other countries as well or if the date is different.
As for other games.... the purchases are much too frequent to list. If I listed every single time this whole topic would just be 10 pages of me posting over and over again. Generally PC games.
