Well its hard to single out
games and consoles. i used 2 like all the systems for various games, that of course was before i was introduced to The World of Warcraft.
My top systems would be X-Box 360 (including the original X-Box), PS 2/3, and the Wii/ G-cube.
I loved the X-box bc i am a big Halo fan. Mainly the first one, among other games, but Halo stands out the most.
PS2 holds the key to my heart, Kingdom Hearts that is. That prolly my favorite game (when it comes to systems at least) and if not my favorite, one of the tops. Theres also metal gear, which i enjoyed greatly, but i dont think i like it better then Kh1/2.
PS3 however has Resistence Fall of Man 1/2 which r fun FPS.
The Game cube has titles like Melee, and RE4, which were my fav games for that system. i also liked sonic adventure battle 2, and of course, Metroid. they would be my favorites for g-cube (not in that order however, it would be to painstaking to attempt to list them in order right now).
I havent played much of the Wii, but i really like brawl. So far thats about it, other then all the remakes.
In conclusion, I like the X-box(s), and Playstation(s) the most. My favorite games would include the Halo
series, (but mainly the first game), Kingdom Hearts, which were some of the best games i've ever played, as well as metal gear and some other fun stuff. Metroid, Melee, RE4, sonic were fun for the g-cube, and brawl was my fav Wii game. But these all pale in comparison to WoW in my eyes. But seeing as how computers were outlawed in this thread, i did not go into detail about it. I hope this has accurately answered the question at hand.
