I held a 31/2 hour demo this weekend at local convention (I was to hold two but sunday I came down with the flu). Those say that Warhammer is convention unfriendly I dont see how, the compontents attracted people. The little downside is the setup compared pencil and paper, but then I was setting up to display all the gooddies. I had two new players to RPG and two regular players.
New player view of the game
*Cards made it easy to figure out a plan during combat
*enjoyed the magic system and had fun with canitrips
*wound system was nice
*both players found it quick to pick up for having never having to play rpgs before.
Regular players to RPG
*The White Wolf player found that it was intresting and enjoyed the feel of game.
*D&D player had a harder time in the combat portion of the game, he felt that couldnt grab distance, movement, or pushing with fatigue. I figure since there wasn't a map out to see with.
All in all the game was great and introduced players to a new game. The group had fun. I have to say that Warhammer screams as one of the better intro games and to be played at conventions. The worse is making sure you dont forget anything as you pick up.
