I enjoyed (and am still enjoying) Oblivion, but I'm a huge fan of Morrowind and I agree with Easykill; it would have been more enjoyable had it been more of the same. On the face of it, Oblivion is better than its predecessor in almost every way, but it doesn't suck me in like Morrowind does. My main issue with Oblivion is that whilst Bethesda have quite obviously gone to a lot of trouble to improve most of the game play elements (combat in particular) I can't help but feel like the atmosphere has suffered as a consequence. When I play Morrowind I feel like I've entered an alternate universe full of bizarre creatures,lost civilizations and mysterious characters. With Oblivion I don't get that feeling, it just feels like pootling through Ye Olde England, which is nowhere near as exciting.
Yes, Cyrodiil is a stunning game environment by all accounts, but it hasn't got the variety of Vvardenfell, one of the things I really enjoyed about Morrowind was walking from place to place and seeing the landscape change, there were swamps, deserts, forests, volcanoes, and weird giant-mushroom things, we had the lot! Cyrodiil by contrast, is mostly just forest and mountains. Beautiful, yes, but a tad monotonous.
Oblivion has better mechanics almost across the board undeniably making it a 'better' game but even when I'm having a great time turning goblins into flaming ragdolls with my Bow of Blaze, I still catch myself gazing wistfully at my copy of Morrowind and wishing I was doing so in Vvardenfell.
Is it just me?
