Well I just played DE:IW for the first time...after being a very big fan of DX. Man, that game sucks...it's not even remotely close to the gameplay I loved in the original. I played the first 3 missions and could not force myself to go on - it was horrible.
On top of that, the settings were hosed and it crashed my computer upon trying to uninstall it. Injury to insult.
I've pre-ordered Thief:DS, but only because I really (REALLY) liked the first two and want to support the franchise. I really hope a vastly different team of coders made TDS - because they severely missed their target with DXIW. I almost think they sabotaged the PC version on purpose just to drive people off the PC and onto the more profitable XB. Utter shite.
