One of the longest-running online-only Massively Multiplayer flight sims is iEntertainment Network's Warbirds, which has survived competitors, massively multiplayer RPGs, the death of the flight sim genre, and its own high fees. The latest version, Warbirds III, went into "paid production" near the end of March and is probably the most substantial upgrade since the game first started running in 1995. Although this version adds new features like an expanded strategic level and an entirely new graphics engine, it still has some of the obstacles Warbirds has always had: a prohibitive pricing structure and an even more prohibitive level of difficulty for newcomers. In a way, it's an example of how the more things change, the more they stay the same.
