bansama: Part of me wonders if this will appear on GOG, Steam and GamersGate for $9.99 and $39.99 on Impulse*
* for those not in the US at least.
Joking aside, I'd love to get the first one again. I've already got 2 and 3 from here, but I have no real incentive to play them without being able to play 1 first.
Don't play 3.
You can safely play 2 without playing 1 first, the only thing you'll miss out on is introductions to characters. It's like BS2 was designed to be played on its own, because their allusions to the first game will either make you want to play it or replay it.
Essentially, if you play Broken Sword 2, you'll be stuck in an endless cycle of playing Broken Sword.
