Hmm...
maybe for nowdays 8 days is pretty long but i was used to play games like:
Heroes of might and magic
Dungeon Siege
Warcraft 3
And those games got such a high replay value that it didnt felt out so hard when you completed the game the first time...
But i almost never play straight action games (except shooters online and GTA games) but it sounds like that more games of that genre got the same play time because in none of the reviews of the internet i read about the short time play...
Maybe i just need to be realistic, gamers of these days doesnt have the patience to play weeks the same game?? (or is that a totally other discussion

)
