I saw the post about the upcoming release of the beta for Europa Universalis IV and how Matopicus, like me, has tried to play and like EU 3, but was unsuccessful.
It got me wondering what was the most frustrating/difficult game that you have ever played and yet had fun with. For me, it would be flight sims; the one that comes readily to mind was Falcon 4.0 as well as the original Deus Ex.
In addition, games that I know are hard to learn/play but I really want to try include the original X Com, Jagged Alliance 2, the Sonanalysts suite (Fleet Command, 688i, etc). I also want to try Arcanum of Steamworks and Magick Obscura, Silent Service 2, the old school Atari games (Balder'sGate 2, TOEE, Planetscape) and A-10 Warthog.
What games have challenged you while still being enjoyable, and what games would you like to try, even though you know they will be difficult?
Edit-Silent Storm Gold, not Silent Service. I cannot protect the President .
Edit (many days later)-Silent Service-> Submarines. Secret Service ->Protect the President. It pays not to post if you are distracted.
