I have to agree. I liked Rainbow Six when it was actual tactical missions - Like the whole mission is on a boat (for example), and you have to map out who goes where, what routes to go etc.
These games at the moment lead you down a path of destiny - Its very one-way. They need to make Rainbow Six single player maps totally open. The game needs more atmosphere...It needs to have no music.....It just needs to be the gamer, and his senses. The whole feeling of stealth/infiltration is gone, and needs to come back.
I do enjoy the new versions, but its definitely dumbed down.
On the new version - I CANT SAY HOW MANY TIMES I'VE PRESSED 'B' THREW A GRENADE, AND BLEW UP MY TEAMMATES. I just cant get used to the buttons coming from Call of Duty 4.....And it doesnt help when I keep playing CoD4 online in between my Rainbow Six single player game. Aaaarrrgghhh!!
