Welcome to the Armchair General forums, OverRunner.
If you liked playing Panzer General
, I would suggest that you have a look at Panzer Corps
. And if you feel the urge to play Panzer General II
you can buy an updated version of it that will work on your new laptop from Good Old Games
for $9.99 U.S.
I haven't played most of the "latest and greatest" PC games, so I will leave it to others to recommend some of those. Digital downloads are very popular these days and retail boxed games are sometimes hard to find. If you prefer the latter, I suggest you have a look at the selection at the NWS Online Gaming Store
If you are interested in online play, the latest craze is the Free-to-Play models which are downloaded and played free of charge. The gaming experience varies from game to game, but if you like tank games I heartily recommend World of Tanks
Good luck! I hope that helps you out.
