I liked Lilarcor, which is why I I'm keeping my fingers crossed. If I do a playthrough with Minsc in the party, I'll always give Lilarcor to him. I find that funny and as a sword Lilarcor is really good. Enchantment is +3, annoying effects like fear and confusion are not an issue anymore... Also, being a magical weapon, Lilarcor could very well still exist 100 years after BG2. I certainly wouldn't mind seeing him, or a similar weapon in the game, possibly even tied to a fun side quest.
