Does the new page give a good overall aspect to what Gaia is?(yes, I'm a grammar nazi, lay off XD)
It does a pretty good job. The soccer net struck me as odd but it's no biggie. XD
The only major problem I see is that, while the pictures are great and the layout is great and it's all really appealing, a new user probably still won't have a clear idea of what they're joining. A little text wouldn't hurt. Especially in the Community picture. I can see why seeing a bunch of avatars might confuse them. Tell the new users how they can customize and personalize their avatars to use in the forums and games. That'll not only explain what those are but pull them in since Gaia's avatars are unique and really cool looking.
Are the images too young or old?
I wouldn't really change anything age-wise. All the images are either of avatars or already existing images on Gaia that are ageless/genderless. The only new image is of the two people and it's a pretty obvious attempt at all ages welcome. XD I mean, we have the really nice, naive-looking newbie in his punk shirt and then we have the more mature (perhaps slightly manipulative XP) woman on his left. It's pretty much an aim at young teens to adults which is pretty much the population of Gaia.
Does it make Gaia look too much like Neopets/Myspace/other sites?
I actually think this makes Gaia look pretty unique. You guys have a nice layout with custom images. The only thing that ties you to any other site is the statement "largest growing community" or whatever it says and I wouldn't take that down. It's honest and it'll make people want to be a part of our already huge community. I think you guys did a great job on this one.
Does the design look good? Layout problems?
It looks a bit long which the only problem with that is that it means that you have to scroll. Maybe if you get the three images underneath the big Towns pic scrunched into one line so it will go Play Games->Community->Join Our World instead of Play Games -> Join Our World |next line| Community. Then you can have the event banner underneath that. This way there's less scrolling. Scrolling may not seem like a big thing, but first impressions are everything. The easier it is for the new member to see what Gaia is, the more likely it is that they'll want to join.
Anything missing? What should we add or change?
Pretty much all I see that you guys should add is some explanation about avatar customization like I said earlier. And another thing you guys should think about changing is the Event Banner. You might want to add a title like the other images saying something like "Participate in Events" or "Follow the Story" maybe even "Be Part of the Story". Or storyline. Whichever suits your fancy. But just something to kind of pull users in instead of just "Which Santa will win?" If I'm a new user, how will I know what's going on let alone care about it?
Should we emphasize more on roleplaying/forum/games/items?
Again, just a bit more emphasis on the whole customizing your avatar since everything on Gaia pretty much centers around the avatar. I mean, your avatar shows up on anything that you do: the forums, the games, your profile, your journal, etc. Otherwise, I really don't think any other feature towers over the other. Everything is equal in my eyes since not every users is into games or roleplay or forums or the items so we want to appeal to a large audience without alienating anyone.
