vanchann: There are enough great games.
Already mentioned Lords of Xulima, Shadowrun series, Xenonauts and Battle Worlds Kronos.

Also you could try Halfway or Bionic Dues.
The Last Federation is turn based too, but turns run simultaneously (like real time with pause in intervals). Check a gameplay video if you'd like.

Unfortunately Wasteland 2 Director's Cut has performance issues (it's unplayable), while the original version runs smoothly on my system.
