eLzar and I played Twilight Struggle a couple of times.
After several failed attempts at it on the Vassel engine (for some reason the engine would freeze or loose connection somewhere between the first and second phases of the game). We sat down and played the copy eLzar owns while he was up in SF a few years ago. I really like the dynamics of the game. The cold wars period usually doesn't lend itself easily to board games due to the mostly covert nature of the war, but this game seems to capture it well. Plus the card dynamics are different, along the lines of Kombat Kommander or Up Front, but seem to work well for the game.
I would suggest giving the game a try. Having never played the game before, it was quite a challenge on Vassel as a first time afair due to the somewhat unconventional game mechanics. Might want to play the real deal before going to the electronic version.
