I'm using a gen 4 i5 , boosted to 3.8 GHz which is the limit for this CPU. I consider it a potato PC, and even so... on a 3.8 GHz core, the game is fluent in the last mission. In my opinion, the challenging part would be architecting this whole thing, from the LAN sessions to mission progression and progress saving for all parties. Not impossible, but extremely time consuming if implemented by 1 person.
