While I've certainly spent a significant amount of time lurking/trollan'/posting on Destructoid, I never really saw any incentive to "join" until I started lurking the C-Blogs more and took note of the truly interesting discussion that takes place here.
My biggest problem with "joining" was that the community is still filled with a great deal of either douchebags or weirdoes, but then I thought "Screw it, most of these people are cool" and joined anyway. There is some truly great discussion that takes place here and I thought it would be cool if I joined in.
Seeing as this post is pitifully short, I'll put up random opinions that showcase my taste. Feel free to disagree and throw me into a pit of fire:
Super Mario Galaxy is the best Mario game of all time and the best game on the Wii.
The Metroid Prime series, as a whole, is excrementally boring to the point that I never finished either game.
The Megaman X series (the first 3, at least) is better than the original Megaman series in almost every way imagineable.
I find 3D RPG's surprisingly bland in comparison to their 2D counterparts.
Games like Call of Duty 4 and Half-Life strike me as the sort that have the interactive storytelling that will push videogames forward as a medium.
The Metal Gear Solid series has writing so terrible that it is insulting to aspiring writers everywhere.
Games with a powerful storyline are almost always more memorable than those without. Unless it's Super Mario Galaxy. :D
Cheers.
Also, Team Fortress 2 makes me fap at night.
