Best in strategy and simulation until October 16th
I'll admit, I'm not the kind of guy who is good at tower defense or RTS (that's more my son) but I played the crap out of Tropico 4 back in the day, so I can personally vouch for the quality behind Kalypso games.
Many of these games can be found at a sharp discount until Monday, October 16th at 1pm EST. If you're a fan of isometric military sims, or isometric pirate games, or isometric...well you get the idea. Kalypso is very good at games with a 45 degree angle.
Below are a few of our favorite deals. Check them out if you fancy a decent sim!
