Im gonna guess how this will work.
The mobilesuits will be rescaled bots, like the mech but bigger. The weapons will be equipable like Regular weps because they will resize with the suit.
Am I in the general ballpark?
Yes and no.
You're hitting upon one of my ideas, but I don't think I'm going to add it until later, that is, if I do add it..
Players will actually be the mobile suits (Normal sized, all the but the builds will be mini) and the weapons will be normal sized.
I was thinking about players that were scaled down, running around with small weapons and such, and they would find bots (Either normal sized or upscaled) that looked like the mobile suits. When they clicked on the spawn brick the suits were on, they would trigger an event (Bot would disappear, player would teleport to that brick, player would be scaled to same size as bot, player's appearance would match the bot's apperance, and the player would be outfitted with weapons, and the players would have their datablocks changed).
