bevinator: While ToB isn't as good as SoA, I still like it. It's got good itemization, for one, and the fights are fun for the most part. I also enjoy Watcher's Keep immensely. I like the HLAs they added, and the shenanigans you can get up to with Time Stop and Improved Alacrity are just silly. They also succeeded in making Druid a decent class again, compared to an extremely lackluster one in BG1/SoA.
On the whole, yeah it's not as great as SoA. But I genuinely do not understand why some people here hate it so much.
Even better than Timestop + IA is to cast Wish, choose the "Time Stop + Improved Alacrity" choice (which isn't actually IA; it reduces casting times to 0 but doesn't remove the once per round rule), and then cast Improved Alacrity. You can now cast any spell with a casting time of 0 and then immediately cast another, allowing you to cast every single spell you know in 0 time.
(Note that this doesn't work in the Enhanced Edition; they changed the effect to actually replicate Improved Alacrity instead of reducing casting time.)
As a side note, the way they implemented Wish reminds me of the MAHAMAN spell from the early Wizardry games. MAHAMAN had no negative effects, but then again, it did level drain the caster (unlike BG2 Wish).
