Go get it.
Hippieman sent me a message on XBL a couple days ago.. the two downloadable netmap packs for Marathon:Durandal, the XBLA version of Bungie's classic Mac and PC scifi shooter, the grand-daddy of Halo, are now online in the Xbox Live Marketplace.
The Escapist has a short article up on methods to combat various forms of motion sickness sometimes related to video gaming.
Bungie fans will recall some of the problems fans had with the XBLA version of Marathon:Durandal that caused motion sickness in some players. It was speculated that the problems were related to the field of vision and framerates being different between computers from the era in which M:D was originally developed and the Xbox 360.
In short, the suggestions are: sit further from the display, have some ginger, and just grin and bear it-- the effect can lessen with time.
Version 0.20.2 of Aleph One, the open source engine for playing Marathon games on MacOS, Windows and Linux, has been released.
