you cant really review this but its great fun nontheless
that's the biggest thing about this, its all the heroes game in one. today its really hard to find the first games but with this you got it all with some extras on top. (for example a big fan fact book) i rather enjoyed it.
the games themselves actually work (for the most part) on newer system like vista 64-bit, but the 4 game gave me blue screen so there are some compatibility issues but the rest worked just fine, even the older games.
one thing i didn't like though was the fact that even though the entire saga was present they left out the heroes 3 based storyline that bind the third and the fourth game together. Considering the fact that those games are just scenarios i think they should have included them. This version is after all called Complete Edition.
All and all these games are well worth the money and i really recommend it
