I know I just got back into WoW but WildStar looks really phenomenal. WildStar is a beautiful looking MMO that's currently in development. It looks absolutely fantastics. The characters look very expressive and the environments look fantastic. It's currently in beta right now and I'm really enjoying seeing how it turns out. There are two factions, the Dominion and the Exiles. Right now it looks like there are currently 6 classes, of which four have been revealed and they all look really cool.
One of WildStar's features is one that I wish WoW had, player housing. In WildStar, your house floats on a rock in the sky and is highly customizable and interactive. There are several different house models, it can get attacked, your friends can visit it, and you can return to it from anywhere at anytime. This will be a really great place for me to log in and log out so I don't log in and have the first thing I see be a mass of people. People stress me out, and having this space to get into the game will be really great.
Another really cool looking feature is Paths. Just like WoW, WildStar will have races and classes but in addition to that it will have Paths. Paths are all about the content that you like to do. If you like to fight, be a soldier. If you like seeing all the sights, be an explorer. If you like to learn all the lore, then be a scientist. And if you like to craft things, then be a settler. Soldiers get more combat content, scientists get missions to examine objects, explorers head to remote areas, and settlers build building and other things. Any race/class can be any one of the classes and having them work together provide great benefits to a group.
There are tons of other things that look great about Wildstar, like movement. It not only has jumping, but double-jumping. It also has rolling and dashing. It looks like it's currently targeted for release later this year.
