OR go try paintball.. if you like the rush you get from playing paintball then you will certainly like playing airsoft.
Airsoft is similar to paintball. You do not need to worry about being marked by paint, you do not have to wear full masks (although some people prefer to and advise it), you have a wide range of different rifles, submachineguns, pistols, shotguns, sniperrifles to suit your preference.
If you cannot get yourself to one of the organize airsoft games in winnipeg then you are better off trying paintball instead of spending money on cheap airsoft guns (this will not give you any feel of the game).
