The epitome of everything the infinity engine set out to accomplish.
Baldur's Gate II inherits the almighty infinity engine - an isometric view game that allows the player control of up to six characters based on the rules to the Dungeons and Dragons game. When I first played the original Baldur's Gate, I thought to myself, "I'm playing DnD without all the pain numbers to keep track of and dice and character sheets and whatnot." It still had some issues back then. Key was the space allowed for in the game. Characters often got stuck meaning you had to spend agonizing time getting out from around a corner and a tight nook in the dungeon. All that is gone now as all the lessons learned making Baldur's Gate have been considered in making Baldur's Gate II. This game has made staggering improvements on what was already an incredible experience. The action moves quickly and allows you much better control of your characters.
BGII starts where BG left off (minus Tales of the Sword Coast) and you can even use your old character. The game goes far beyond as you learn more of your character's dark history and grow in power. This epic finds your group ascending to tremendous levels of power and the corresponding spells and abilities are truly impressive - all the while keeping the rules nicely in the background. If you like RPGs and after all this time haven't played BGII, well, dated graphics aside you owe it to yourself.
