Leroux: It's just a matter of preference and accustoming. Apart from Brothers: A Tale of Two Sons I haven't played any game yet that wasn't just as playable with keyboard than with controller. Naturally, players used to controllers will feel more comfortable playing with one, players accustomed to mouse (and keyboard) will do better without one. That being said, I was pretty much a keyboard/mouse player only, too, before I finally caved in and got me an XBox controller for the PC, and now I actually do enjoy playing platformers and brawlers with it instead of with the keyboard. It's not necessarily easier or better, like I said, it's a matter of preference and getting accustomed to it. Just saying, if you give something a chance and familiarize yourself with it, there's a chance you'll actually end up loving it. Or not. :)
One thing that gets lost in translation to keyboard and mouse is the vibration effects though. And depending on your preferences that can be both a good thing or a bad thing. But some games (like Brothers) actually use this in significant ways, not just for show.
I do try playing with a controller every now and then. But it's more along the lines of "for lulz" or "I appreciate the fact that I can stand up, and walk around the room while still controlling my avatar (not possible with a keyboard, even less with a mouse)". :)
I don't even have a problem with the famous fighting games' Dragon Punch move (down, forward, forwarddown) or half-circle-backward kind of moves on keyboard while having difficulties with the controller this was made for, namely the arcade stick.
I think that the advantage of a keyboard is that you can use all of your fingers at once and there are many buttons within reach of each one. With a controller your ring finger and pinky is mostly just used to hold your controller. ANd index and middle are so strong and fast, the thumb is just awkward and big...
Maybe it's because I played piano and bass guitar...
I do agree however that certain games were designed with certain controllers in mind and that pads, joysticks, arcade sticks and all other have their own respective advantages in certain cases... It's just the amount of keyboard hate is overblown, the poor little keys feel discriminated! And some people justify it as something totally objective when it isn't!
Ok I'm getting a little off the topic here. So, to redeem this post: lots of interesting suggestions, I like it! Abbe's Oddysee is playing great atm, the games with such a unique character like this one are so rare in gaming history. And the graphics didn't age much at all, it's freakin' 1997! If this wasn't an already established IP, no AAA studio would have been keen on kicking off an entirely new franchise like that, I think. So much new gameplay ideas for it's time, story, art and it plays so smooth and responsive... I'm absolutely a fan of this, after finishing first level :) Psychonauts also great. Lot's of cool dialogue, voice acting top notch, level design a total surrealism.
