UFO:Enemy unknown used to be, but this has modernised and surpassed it. This is a game that has been well thought out, with the annoying bugbears of the old version (such as full alien mind control/Blaster Bombs/Proximity Grenades) removed. The developer has continually updated and improved it since its release, with V1.5 coming out soon (which includes lots of fixes and addresses a lot of the complaints discussed here such as Line of Sight issues). A great 1st game for Goldhawk, and their community support is 2nd-to-none. If you like turn-based tactical combat then this is for you.
