I played 1 game with someone who had never played before and helped him figure out how to play. Which of course probably made his opponents hate the game because they got rolled over... :/
Then, outside of the demo, I bumped into a brand new player who had just picked up the game. He said he was brand new, so I kicked our 1 opponent at the time from the lobby and setup a comp stomp so me and a few buds could teach him the game. I think that was a better approach.
Anyway, greetings to Varun03. Welcome to the community! For those of you who are interested in teaching new players in the demo, I suggest this as well. Set up a comp stomp (*hope you can do that in the demo*) and teach new players the basics.
