Having played these games growing up, and rediscovering them on GOG, I was mostly playing the official WADs with the 3rd party GZDOOM app. But I have to say, this upgraded collection blows everything else away! TYhe gameplay is ridiculously good with full keyboard and mouse support, the new music (you can opt for the original soundtarck) is fantasic, and the No Rest For the Living episode is really, really good! I'm really enjoying this.
I already own this on another platform but had to give it some love here. If you enjoy X-Com-type games but struggle a bit with the difficulty or complexity, you might enjoy Chimera Force. I found the game really solid and fun. It's a lot easier than standard X-Com, somewhere on par with the Shadowrun games. The story and characters are pretty cool, but it's the unique Breach Mode and general combat mechanics that appealed to me. And of course, the setting! Getting to play with human and alien characters with their own abilities was so much fun. Hard-core X-Com players seem to find this title a little too simplistic or easy, but I really enjoyed it. Just crank up the difficulty if you're worried about it being a little too easy. It's very customizable.
