Arcade flight sims dont come around that often but we have one on the near horizon right now.

Jane's Advanced Strike Fighters is a flight simulation with both single-player and multiplayer modes (versus and coop) that sends players off to duke it out on massive battlefields in modern fighter jets. With 16 missions featuring land, sea, and aerial targets, the game world spans more than 65,000 km². The system requirements for JASF are out now so lets take a look...

JASF Minimum System Requirements
