Bastion repetitive? Only if you think The Legend of Zelda a Link to the Past or Secret of Mana was repetitive. Its easily (IMHO) the best SINGLE PLAYER XBLA experience you can get atm. I really dont think anything will top it. Bastion and its DLC is a must buy for nearly everyone at half price (dlc is only 80 MSP).
Im gonna ask again because i cant find any concrete info... is BD1943 still active? Over at the gamefaqs message board the newest post is like June of this year with no responses :P I have Halo 4 now (love it) and CS:GO love it too but havnt booted it up since last Tuesday. Should I pick up BF1943? Its one I have always wanted to own, but if its not active its kind of a pointless buy for me.
Bastion was the first game on 360 I bothered to get all the achievements for. I loved it. As for BD1943 the PS3 community is still very active so I'd say it's a good sign that the 360 one is as well. You can also just download the demo and see for yourself.
