Still haven't bought Super Street fighter 4. Just can't bring myself to get into it again after I rinsed the first version too much. My arcade stick is dead now as well.
Been playing the shooter Ketsui. Can get to the 4th level on a good run now. Don't think I'll ever beat it, but it is one of the best shooters I've got so I'll probably be going back to it for years.
New Super Mario Bros DS - The gameplay is literally perfect. It's as fun as it was in the NES days and the new power ups make things more interesting. My only slight concern is the difficulty, I've only played for about 2 hours and I'm on world 5, it's nowhere near as difficult as the Wii version. Either way it's a cracking game
I've been playing Portal and LEGO Harry Potter these past couple of days. LEGO HP is pretty cool considering I don't really like LEGO games, it's a quirky little platforming game. Portal is amazing of course, although it's starting to piss me off a bit ¬_¬
Watching my brother play Mario and Sonic at the Olympic Games. He picked Sonic and a swimming sport. I laughed my head off when I saw that he had a life jacket and was practically doing the doggie paddle.
EDIT: Apparently it's called underwater running. How appropriate.
