two questions

Well, as for me, I never paid money for games and I never will! I'd rather buy a game disc in a store, and it will stay with me for years, and I can install it whenever and wherever I want! By the way, I've had the Heroes anthology disc for about 2 years now, installed it about 100 times due to reinstalling Windows or just Heroes crashing on me)) but this disc cost 200 rubles, and it has all of Heroes 1-5 and all addons — all in all, a pretty nice purchase. But downloading games for money is utter nonsense! Your computer breaks down because of some crap and the money's wasted. Also, you can't always transfer them to something like a flash drive or other electronic media. So it's better to buy discs, from trusted places. Much more reliable, and you won't pick up extra viruses)))
P.S. And in my opinion, it might even be cheaper)
P.P.S. Is it just me, or were there links on HeroesWorld somewhere to download the third game?
