Since I'm here already, I'll begin.
NBA Live 08 (PC)

As with the last thread, I'll start with the NBA Live series. As much as I like the 360 version of last year's game, that's how much I dislike the PC version. It'll be worth a year off from a PC release if it means the end of this engine. I was hoping after all the issue with 07 PC we'd see a turnaround but sadly that wasn't the case.
NBA Live 07 (PC)

Disappointing but much more playable than its immediate successor thanks to an official update which resolved some of the issues. It hasn't been a good couple of years for NBA Live on the PC to say the least. I'm hoping for better days ahead as far as a return to the PC platform is concerned.
WWF Attitude (N64)

I remember being so pumped for the sequel to WWF Warzone and feeling really disappointed after playing it for the first time. Looking back, it's not a terrible game per se but few of the talked about features made it to the final game and despite the expanded and updated roster, it didn't feel like much of an upgrade. Perhaps it's because I'd grown fond of the engine used in WCW/nWo Revenge that would later be used in THQ's Wrestlemania 2000 and No Mercy once they got the WWF license.
