Lag notwithstanding, I would recommend Shadowrun Chronicles to anyone who enjoys the Shadowrun universe and enjoys turn-based strategy games. If you liked Shadowrun Returns, you'll probably also enjoy Chronicles, although you won't find the same depth of story just yet. The developers at Cliffhanger promise much more story that will be molded by the players as time goes on.
All in all, I'm very pleased with Wasteland 2 and I would highly recommend it to anyone who enjoyed the original. But for those who never played Wasteland 1, the appeal of this sequel may be a mystery. My advice for you is to pay the $5.99 for the original game on Steam and play it to the end. Know your roots, kids! And get off my lawn!
