Big open worlds to explore between 200 to 400 square kilometers Two modes of play: Normal and Hardcore Combination of first-person and third-person perspectives Meld of PvE (player versus environment) and PvP (player versus player) Strong Role Playing Elements Multiple playable characters with customizable features Unique social elements, including bounties, help requests, trap setting, etc. Safe settlements where players can purchase, sell and store items as well as post notes for other players Dozens of unique skills that can be learned and improved Up to 250 players per game server New weapons and items become available as players explore the game world Full developer support with regularly scheduled, free content updates Dedicated public servers as well as private servers that can be completely self-managed in game client Single purchase, downloadable client with ability to play full game without subscriptions or requiring in-game transactions If those items in italics are incorporated, I'd say I'd probably go with War. I like the idea of a safe zone. Maybe like the military zone in 28 days later (granted, they were a bit dodgy, but they were safe - at least until Cillian unchained their zombie pal). The idea of bounties is good too. However, I have doubts about 250 player persistent world. I mean, it's not impossible - WoWarcraft and other MMO's do it all the time. But for a FPS?
