WGTT = (Self-proclaimed) World's Greatest Tag Team, made up of Charlie Haas and SHelton Banjamin. They're awesome.
Smackdown is really fun though. The storylines are great so far, and the matches play flaylessly. Just don't take a cruiserweight against someone like Brock Lesnar or Kane, because you WILL lose. They added a weight class feature, so you can no longer lift someone twice as big as you, and your attacks won't be as damaging, causing you to develop strategy for a change.
THUG, I haven't played much. I really want to, but I also feel like I should wait until I get a digital camera so I can map my face onto the skater. I don't know.
One thing I like about it, is now there are difficulty levels, so if you felt the last game was too easy (which you shouldn't, you fucking whackjobs), you can pump up the challenge. I also like how you earn stats now. Instead of winning or finding points to attribute to the different areas, you earn points for a specific area by completing certain skating tasks.
For example, to increase your Air stat, you need to clear a certain amount of feet when doing a transfer. There seems to be 3 challenges per category, per area. But since I only skated around Jersey, I can't say for sure.
