There are 8 other maps, and there will most likely be more coming by way of dlc. I am also disappointed about the amount of maps, but oh well they put a lot of crap in the game that makes up for that.

I prefer bright daytime maps to dark or dull maps so I don't mind. You can use filters to change the brightness and other stuff so things might look different and I think you can still forge on the other maps if you want might be wrong though. 
 
Besides Halo 3 had lots of forge maps which were all taken form Sandbox which was just a desert and they all had a different feel, to me at least.

I'm so bad at multiplayer FPSs that I usually don't even have time to take in and judge the scenery as it takes every once of my concentration just to try to stay alive.
 
...not to mention actually getting a kill :P

I've noticed that too but maps like the ivroy tower remake look so pretty im a happy boy. Does anybody know if theres a snow level? There my favourite Halo levels...

I like the Forerunner architecture of Forge World, and I definitely prefer outdoor to indoor when it comes to the setting of a multiplayer map.
 
To each his own I suppose.

I'll get back to you in a month.
See the community in action!
Don't underestimate people, they can accomplish a lot even with limited tools!

They look great to me and I can't wait for Forge World.
 
Giant Bomb Forge World Night this weekend?  Wait for more details...

The Ivory Tower remake alone is enough for me to disagree with you. That's one of the prettiest maps I've ever seen.
