I went with 3, but now I think I should have gone with 4. It was a bit of a mixed bag.
I love the new look for Zelda, don't doubt it will be brilliant-but that demo was awkward and messy because of technical issues. It dampened my excitement considerably, I was hoping for a great demonstration of the controls. I was also hoping to see more varied areas of the game, and can't deny I'm disappointed it will be 2011. It's going to be a long wait. Kirby looks fantastic, Metroid and Donkey Kong are must haves for me and Goldeneye and Epic Mickey were great examples of good third party support. The lack of Xenoblade and Last Story was also disappointing.
Mario Sports Mix didn't do much for me. Wii Party I was actually pretty interested in. Golden Sun I was very excited about.
3DS-the machine looks fantastic. Kid Icarus gave me goosebumps. I missed the video after that because my feed failed. I was disappointed they didn't confirm more games, really. I believe the potential of the device is great, and am hopeful more games will emerge from the show floor.
Not sure what to think right now. I think show floor impressions will enthuse me more. It's all about how these games and devices play, after all.
