Off Topic - That game was random as hell
On Topic - I like C&C and its possible but thats going to be hard i mean, its possible but consider this:
- People will be joining and leaving: wtf are they going to do? just watch?
- People building outside of levels: As far as i know, all the levels in blockland are infinite (except for slate?)
- The Lag: Making the units (Bots, vhiecles, ETC) will lag cause whos going to attack with one tank.
- Complex Coding: I would do it but i have no idea and other people are either busy with their new add-ons or they are just being lazy (I wouldnt blame them)
- Motion Builds: Every C&C's buildings would move (Crane moves for construction yard) which in blockland, theres no such thing as a moving brick and there are reasons why.
I like the idea but the fact that the above issues are... well... issues to consider, it will take a while to manage this.
