A couple(literally two) people have mentioned that either the Source engine won't satiate the requirement for big maps, or that the goals of the project are too great. So to clarify things to repudiate any further questions, A.) the game is not open-ended, therefore the map size of the Source Engine will do fine, and B.) the game is a concept, things change, and already have.
Among these changes are:
• Removal of the Hunt mode, far to large, open-ended will not work
• Weapon count of 100+ was a bit much, I have however fully design more than 70% of the weapons and am at roughly 40 weapons.
So, I understand how you guys feel. Just keep in mind it's a concept. It's also my first publicly released mod concept. Thanks for your understanding.
