Shadow Complex, so far for me, is just a lame wannabe Super Metroid with some serious AI issues.
I didn't enjoy Ms. 'Splosion Man so much. The humor was, at most part lame, and when it did work, it was only in music videos and non-gaming situations. The actual platforming felt very much like current 3D Sonic games, though slightly more difficult just because of the lack of the ability to see what's ahead. It's got some major problems with borrowing a bit too much as an attempt to pass on homage, and Ms. 'Splosion Man, herself, blends into the background quite a bit.
Yeah, so forgive the mini-review, but Ms. 'Splosion Man (in single player) just wasn't up to my grade. I'd rather spend more time playing Donkey Kong Country Returns. I know the price is a lot different, but if I'm going to spend my time playing the game, I want to invest that into the best stuff I can, right?
Edit: As for Bastion, current rumor has it a PS3 version is a possibility. I hope that happens, just so more people have access to the game.
