you guys need to keep in mind that you have to keep a cap on things, beacuse the more items you have on a map the laggier it gets, if you have ever spawned ALL THE VEHICLES in Reach, and let them slide down a slope, **** gets laggie quick, so you have to keep a limit if youre the developer, because with the pelicans and phantoms in matchmaking there would be alot of lagg. just keep in mind.
i do like what u guys are saying though, and i think it would be great to GROUP things, such as, a ship that u built in forge and you want to move it all at the same time.
