No! Forge World on Halo: Reach is completely free, provided you have the game and Xbox to play it on!
You might like lost planet 1 or 2 or section 8 which are games very similar to the halo series. <i was asking for a game with a similar mode to halo reach's forge mode
You can't set the time limit in forge
Yes, but you'd have to have a timer on for the game.
Yes, there are custom game lobbies, creatable game variants, and a different variation of the one in halo 3. This different variation of forge is a little different but alike in a lot of ways. so yes there will be forge.
You only get it when you are doing forge mode
at the beginning of the game before you start it, put game type: oddball in game options.
Yes, Halo Reach does have a Forge mode, it's found in the main menu. Further information: Scroll down in the main menu until you see the Forge option, select it, and you will be able to choose which map you wish to edit by selecting a map, you then make sure that you have put the setting on basic editing so you can use the Forge editor, then have fun playing with the forge! Happy editing :D
invite more players to your game and tell them your design of the map that you want to create
You can't unless you mod which can miss up the game hope this helped.
I would say Forge, depending on your amount of activity.
play a forge created game that has the upgrades placed in the map, or change the game settings in a custom game.
