I confess. I'm a RPG addict. Can't resist. Not trying. For those of you unfamiliar with the acronym, RPG stands for Role Playing Game. That's where you take on the role of a being other than yourself and interact with others in a predetermined environment. Maybe that definition is vague but so is the term "roleplaying". Personally, I'm not gonna get into defining things because that just promotes unilateral thinking and that ain't my bag. Instead, here's the information on the games I currently play.

Online RPGs:

My characters
Bryan - WW Werewolf: the Apocalypse (kinfolk)
Enitocin - Star Wars d20
Declen - WW Mage: the Awakening
Callus Shieldbreaker - Fantasy RP (dwarf)
Jaonh d'Vard - Fantasy RP (half-elf)

PC/Multiplayer:

The Baldurs Gate Series:
Baldurs Gate
Tales of the Sword Coast Expansion
(above two combined to create The Original Saga)
Baldurs Gate II: Shadows of Amn
Throne of Bhaal Expansion

I've been playing this game since it was first released in 1998 when it was voted RPG of the Year. Since then, I've played and replayed it and have never played the same game twice. Later when the sequel (BGII w/ToB Expansion) was released class kits, additional races, romances, strongholds and tons of spells and items were added. Furthermore, BGII and ToB were built on the same Infinity engine as BG/TotSC so it allows for importing your original character(s) into the new game. I can't even begin to give all the information on these games on this site. I suggest visiting Interplay and, once familiar with the game, TeamBG for mods and customs. If you are into hex editing this game is only limited by your imagination.
