Seconded. This is an area where I think Crate pulled it off flawlessly- game retains that old school look and feel, while at the same time modernizing textures and particle effects and stuff. The end result is gorgeous and a huuuge part of the charm of this classic game.
@Klark i agree with just about everything else you said though. Especially starting the kickstart for Crate to work on GD2! But, to be fair and respect all the hard work and time they put into GD 1, i want to give them a break from GD for a while. Besides they have Farthest Frontier coming out next which looks very interesting, and are working on other stuff as well.
I think GD 2 will be best if Crate is able to take a break from it and return to it later, refreshed. I love the idea of a kickstarter to support GD 2 efforts though- maybe whenever they decide to venture into GD 2 territory we could all jump on that idea and give them a bunch of money to help fund it!
