DOA4: a fighting game... that's about all I can really say. The female fighters wear less clothing than they should (hey, i am a conservative fellow), and the overall visible contact between fighting characters is alright, but it looks unrealistic sometimes. The graphics are pretty, but that is to be expected from the 360. I haven't owned a fighting game before, so this was a good experience I guess, it wasn't that bad, and I am still playing it on and off; it is challenging but not impossible. If it didn't cost such a pretty penny, i would recommend it.
Oblivion: More fun that I expected. The graphics are really nice, and I especially enjoy slashing dead carcasses.
Suprisingly, the back of the box says it is rated "teen", however, there is drinking and violence and much blood (especially in the arena), which i guess are welcome to me, but it should be rated M for those little kiddies.
There are numerous quests available, and one can play however they like, joining evil guilds or nice ones, flying through the main storyline or taking precious time exploring every nook and cranny while doing multiple quests at once. Good job Bethesda, you delivered.
And SS, you really need them to work on their face models. I mean, there is not one remotely good-looking female NPC on that game.
