Games that I actually bought (In no particular order):
1. Battlefield 2142.
Tried as I might, I could find no way to make this blatantly imbalanced shooter appeal to me, even back when I was more accepting. The only time it gets now is when I play bot matches with my one friend that has it. It was simply the most frustrating experience I've ever had in a shooter.
2. Mass Effect.
After getting over the new game excitement, I saw it for what it was; a repetitive 3PSRPG with a background style that made it feel like it was Star Trek with a different paint job. I haven't gone back since and won't be buying into the sequel.
3. Dawn of War II.
I appreciate the music. I appreciate the WH40K Universe. I appreciate that the Space Marines weren't just guardsmen with power armor in this sequel. But because of how empty the game felt, with its uninspired, repetitive campaign and hyperfast multiplayer, I feel really disappointed.
4. Here's a first: StarCraft.
I loved the game when I was a kid. But that was back when I didn't think. Almost literally, if my memory serves me right. Now that I look back at it, it feels like the game's ridden around on its map editor. The multiplayer was boring and dull for me, while the community UMS maps - the only maps I ever had fun in - always left something to be desired. And, speaking of the community, it'd gone to utter shit by the time I'd made my first online experience there. Nothing but Koreans, douchebags, and idiots. And it's gone further South over time. To be quite honest, I don't know what people see in this game anymore.
Games I don't actually own (Again, no order):
1. Civilization III/IV.
I like being at the head of a fictional nation. But only when it's actually enjoyable. With the uninvolving and, at times, ridiculous unit combat, the mind-numbing length of the TBS system, and the cheating AI, I can find little happiness in these games. Thank God I didn't waste any money on them.
2. Doom 3: Resurrection of Evil.
I loved Doom 3 to bits. But when I gave RoE an extended trial, the ending absolutely killed it for me. It was fun and different, then bam. A boss fight that's more frustration than it's worth. I may pick it up later to play through it with my friends, but I've no real reason as of now.
