I've attended Phoenix Comicon and had a good time.
i enjoyed walking up to a table to play new games and meeting new people. The games were free and it was a good experience.
what can I expect at GenCon?
1. Are games free to play
2. Do they require a sign up?
3. Are people friendly explaining a new game?(I have a nice collection but referring to games I don't own or play)
4. The events do they require a signup beforehand?
that lifesize Dunegon seems cool
Thanks for any advice :)
