I bought CE tonight, possibly against my better judgment. I want to support the devs who put this together over at DigitalFroggies, and based on the game's good points, they are worth supporting. But the lack of communication and clarity about basic information (has a patch been released? some say yes, some no? how can we tell?) is truly exasperating.
As Queeg and others pointed out, the performance gains are very real. Load times are *much* reduced, which is great. Plus, the game is visually sharper than Gold. I can play at 1920x1080 without eyestrain -- couldn't do that with Gold. These improvements alone are worth the price of admission.
But I can't play for more than a few turns before the game becomes terminally laggy. In that sense, Gold is still way more stable than CE.
I really hope DigitialFroggies can pull their act together. CE has the potential to reinvigorate a truly great game, but I fear the glitches and lack of communication about what is going on with the state of the game is going to scare away potential customers. I held off purchasing because of that, but tonight thought, what the hell, i'll give it a try. CE will be worth every cent of the $20 pricetag, and then some, if the devs can right the ship of what has been a fairly botched initial game release.
