I signed up only cos folks hv helped me with tips on games, so here goes. I've played orig UFO: En Unk for 15 yrs (not all 24hrs of em), & never tire of it. I've tried many others : I cut my gaming teeth on board wargames in the 70s, & for me the orig UFO is the best PC wargame of all.
The graphics are Neanderthal, but those of chess, poker & other great games aren't scintillating either.
The tactics & strat r outstanding challenges. The game always comes up with surprises: u can never let yr guard down.
Working out how to win takesa lot of exploring different strats, especially if you set hardness to Superhuman.
Time to play: As long as u like. It can take > 100 battles. Each battle takes 10mins to 2 hrs depending on how serious u r to win the whole game. Barrelling thru is guaranteed to get u wasted.
If this new "imagination" of it is half as good, get it. Better still, get the original. (U can, from Steam, et al.). But don't get married or get a job, you'll never get round to 'em.
