With all the hate for Dawn of War 2 in this topic, I feel the urge to stick up for it and say that I for one find it to be an incredible experience that was a huge improvement over the original games generic-rts style play. I love the frantic fast pace of the multiplayer, the incredibly destructive powers of the units, the tight focus on units and micromanagement over base-building and resources. The music is amazing, the visuals stunning, and it's just damn fun watch in action! I love it!
Mind you I was never particularly interested in the campaign to start with and so didn't particularly care when I found it somewhat boring, although it certainly had its moments. The Chaos expansion campaign is supposed to be extremely good though, although I've yet to have picked it up myself.
Anyway, as for sequel I thought 'failed'? Well.... I wouldn't say it was a 'failure', because it wasn't, not by any means. It was in fact a massive success that bolstered a once obscure developer into fame. And yet I just can't help but find is disappointing. I had such high hopes, and yet within a week I was bored of the game and have barely touched it since.
Elder Scrolls 4: Oblivion
*fixed*
I just didn't like it. The story was... blarg. The environments, although visually stunning at the time, were... blarg. The characters pure blarg! Everything about it was BLARG! And I'd been so damn excited for it too; Morrowind was at the time one of my favorite games. I played that game endlessly, explored every last cave and forest, read the books, gathered the loot! Countless hours invested into Morrowinds rich and exotic setting.
And yet I was bored of Oblivion within a week. *sigh*
