An interesting item at IMG today, about an upcoming game that could well be a rival for Halo: WWII Online. Like Halo, the game boasts unified land and air combat (and sea combat, too), and is due for an open beta in Q2 2000.
Not many screenshots to look at, though the descriptions are fairly interesting. The persistant online world sounds like a very ambitious version of Warbirds... one to keep an eye on in coming months.
