A couple of weeks ago, I was puzzling over the fact that besides a few golfing and racing games, we don't have many sports games inside the MMORPG genre -- we leap right from sandbox sport fishing to full-scale murder with little in-between.
I dunno whether CCP's new VR venture will count, since it's multiplayer but not MMO exacty, but it's definitely in the ballpark, pun intended: It's called Sparc, and the MMO studio is calling it a "unique virtual sport" where "players connect online to compete with each other in fast and fun full-body VR gameplay." Unlike CCP's other games, this one won't be set in the EVE Online universe in any way.
"Sparc's skill-based, full-body gameplay makes for a fast-paced and fun physical sport. Players use their motion controllers to throw projectiles at their opponents from a distance, and in turn defend themselves by dodging, blocking, or deflecting the incoming attacks. Players can join one-on-one matches with friends online or find opponents via matchmaking. Sparc enables players to connect and compete in an online community. [...] Sparc includes multiple two-player game modes as well as single-player challenges and training modes, plus a range of customization and personalization options for competitors."
