I'd like to run a small poll, but you can comment and add your own thoughts to it. Just saying numbers might not be totally helpful.
The questions I have in mind are:
1- How big are usually your maps in Radiant units?
2- What should be the maximum size, in your opinion? (For various gametypes, let's consider TS, CTF and BOMB.)
For now that's it, but you can add other points in case I forgot something.
