Pheace: I wouldn't mind hearing some other recommendations for that collection ^^ Men of War perhaps? I doubted on that one last year.
It's a great tactical wargame(or RTS), and you can try the multiplayer beta of it's successor,
Men of War: Assault Squad. It's a more polished version, but it's essentially the same game.
I would advise against buying from YuPlay. Afaik they use some kind of DRM based on Securom, and their games are generally overpriced. I mean come on, Theatre of War 2 Kursk costs 30€ on 1C's own distribution system, but you can have it for 19€ on Steam! lulz
Faces of War is the prequel of Men of War, but it's obsolete, because there is a mod for MoW with the levels of FoW.
MoW also can be had for very little money, as they regularly discount it on Steam/GamersGate, and usual sale price is 3-4€(5-7€ for Red Tide MoW expansion).
Theater of War is also nice, but its freaking hard, and its sequels are much better imho.
I can't comment on Blood of Europe though.
