I'm doing a rebel campaign on Sahrani (CSAT is opfor, FIA are rebels), using the redone map that has more interiors. I'm also using the 64-bit executable since it seems to perform better in general on my computer (Ryzen 2200 with about 8 gigabytes of RAM). I've got about 800 total CSAT on the map, and about 100 rebels. Careful placement of TAOR's seems to make it run smoothly. It's been tricky because the central land bridge with the city in the middle becomes a chokepoint where units bunch up.
I'm primarily a singleplayer oriented gamer, and I like the GTA style gameplay that the asymetrical setup produces. I've also made an Unsung Special Forces campaign on the Lam Dong map.
ALiVE is probably the most amazing mod I have seen for any game. I'm going to release my missions and if people want to mod them for multiplayer, that's OK. I don't quite understand the intricacies of multiplayer setup, though.
