referring to the comments by mr bean, yes, LAN games are considered multiplayer as well. after all there are more than one player on the same game session.
multiplayer is a double-edged sword; it can be a nightmare or already has. at the same time though probably not for the same person, multiplayer can be so much fun, especially LAN games among close friend(s). relationship is strengthened, maintained, & u get 2 hear your buds scream for help or just enjoy friendship by sharing potions, weapons, etc.... . this can happen only in controlled environment.
among forum members that i know & respect, i believe this can be achieved. but then, chatting in the forum & playing multiplayer session are two different things. who know? we have to wait till DD2 to come out to know.
