I got Spellforce in the sale :D
But...
...I fail at it.
:(
Therefore...Spellfarce.
Seriously, though, no matter how much your avatar looks like Gandalf, standing him between the goblins and your army will not prevent them from reaching your encampment, no matter how many times you shout 'YOU SHALL NOT PASS' and pound your mouse against the desktop.

You're playing it wrong, you're supposed to be Sauron and put a crapload of minions between you and the enemy

Did you have your mic on mute? If not you need to yell louder. The goblins can't hear so well after all the fighting.

Yeah.....I think that game helped me when I played Warcraft....Heroes will not last by themselves.

You might get more gameplay tips from the Spellforce forum, but I've got no idea how active it is.

This is Spellforce 1, not Spellforce 2. :)

Here's a solution to your problem, choose the guy with the chaingun. No one's going to pass through thousands of rounds per minute. =P

As of a year ago, not very. However, the search function was my friend; pretty much everything has been covered already. It helped me build my character as well as find tips for certain maps.
EDIT:
Uh, duh. You probably meant the Spellforce forum at GOG. I read it as meaning the Official Spellforce Forum.
The forum here at GOG was not very helpful to me, but I bought Spellforce Platinum in the first week it was offered at GOG. Perhaps now it is a little better. I would still search through the Official forums though, it was a great help to me.

That's the one. I probably should have clarified or linked to it, but I felt that would seem too much like me playing forum moderator.
