So if you like the Blitzkrieg Anthology here on GOG, maybe you want to check out the following games, too! Those are similar to Blitzkrieg, although mostly newer. However, you should try them:

- Sudden Strike series: http://www.mobygames.com/game-group/sudden-strike-series
- Blitzkrieg 2 Anthology: http://www.mobygames.com/game/windows/blitzkrieg-2-anthology
- Codename Panzers series: http://www.mobygames.com/game-group/codename-panzers-series
- S.W.I.N.E.: http://www.mobygames.com/game/windows/swine
- Company of Heroes series: http://www.mobygames.com/game-group/company-of-heroes-series
- Theatre of War series: http://www.mobygames.com/game-group/theatre-of-war-series
- World in Conflict series: http://www.mobygames.com/game-group/world-in-conflict-series
- Faces of War: http://www.mobygames.com/game/windows/faces-of-war
- Men of War series: http://www.mobygames.com/game-group/men-of-war-series
- Soldiers Heroes of World War 2: http://www.mobygames.com/game/windows/soldiers-heroes-of-world-war-ii

Maybe I have missed some games. If so, then I will add them to this list, if you post them here. However, this should give you a good idea on which games to start. Enjoy! :)

A fine list of games, Company of Heroes is a fantastic game.

Yes, a very fine list. In fact, Soldiers Heroes of WW2 is here at GOG

There are many more games using Blitzkrieg engine, meaning, more look-a-like and playable wise games. Like:

Talvisota - Icy Hell
Cuban Missile Crisis
Cuban Missile Crisis - Ice Crusade (expansion)
Great Battles of WW2: Stalingrad
World War I

And then there's Frontline: Fields of Thunder, who use Blitzkrieg 2 engine.

I wish Sudden Strike Universe will come soon to GoG. Let's hope.
