The wikia said this:
"It appears Interplay has reached an agreement with Bethesda. The Fallout Online site now states "Fallout? is a registered trademark of Bethesda Softworks LLC, a ZeniMax Media company, in the U.S. and/or other countries, and is used by Interplay under license from Bethesda Softworks LLC. All Rights Reserved.
When Bethesda was* still in dispute with Interplay..... "
*Past tense.
So, is the legal crap over with?
Can we finally discuss the MMORPG?
