Forge World in Halo: Reach

Not really relevant to anything we're working on but I figured it's somewhat related to game design in general (Forge World being a level editor). Forge World is basically a huge world in which you can create a level inside of it using any amount (big or small) of the world you choose. Most Bungie made levels made with Forge World only use 1/5 of the space (guessing) so there's plenty of room to work around. If you really wanted you could use teleporters to navigate the huge terrain in an Invasion map or such.

The good:

• You can edit coordinates for each piece you place so you can line things up almost perfectly. 
• The different physics modes (Normal, Fixed, Phased). Normal lets object react to explosions and stuff so you can move them around the level. Fixed lets the object react and collide with other objects while you're placing it (also good for making things line up and NOT overlap) but it doesn't react to explosions so once you place it that is where it'll stay. Finally, Phased allows you to overlap objects so you can build stuff in the sides of mountains or inside of other buildings. 

The bad:

• No undo button! Even if you could just undo your last move that would be greatly appreciated for when you accidentally delete something. 

Features I wish they had:

• The ability to make myself the only person that can edit the map and anyone else in the game can only play and not move my stuff around. I like showing my friends the progress on my level but it always ends up with everyone dropping in stuff all over the place... It's a good thing to save right when someone joins and don't plan on doing anything productive while there's someone else in the game because they may fly to some random corner and place 47 warthogs in the corner of the map. :) 
• To make objective gametypes (capture the flag, etc) you need to change the gametype before you enter the game. There's a gametype called 'Basic Editing' which just lets you edit levels without scoring or objectives and that's what I always used. When I wanted to add flag spawns to my level I had to quit out, change from 'Basic Editing' to a capture the flag gametype and then I was finally able to set some properties to actually get my flags to work in game. It's not really a bad thing but it's a little bit of a hassle to change through gametypes to get all of my objectives to work.
