You have a clear 2 tear attack for paintball, One is the rec ball which is a great place to start. Its the one in camo gear where you get to do scenario games and rescue the fort or attack the bridge. Most people will have tried this first and decided if they like it. All the gear is provided and you just need to worry about having enough cash to cover your day out.
Second is the tournament stuff where you play with your own gear. You play on specific fields as can be seen in pics on this site and others.
Its a different way to think of paintball but you have to choose what is right for you.
