There is literally no reason NOT to buy this game now that it's on sale for 50% off. This game takes everything Larian got right with Divinity: Original Sin and made it that much better.

Hilarious dialogue, rewarding co-op play, an incredibly engaging combat system, free content patches, character customization and dye-able armor, unique companion interactions, and a VERY engaging story and world are all just the tip of the iceberg for what many regard as a masterpiece in RPGs.

If you're excited about Larian's upcoming Baldur's Gate release, and you somehow haven't played this game or Divinity: Original Sin, do yourself a favor and pick them up. Even if they're not on sale, they're absolutely worth the money in gameplay.
