Personally, I believe that the choice is yours depending on whether you are willing to pay a lot for a hobby and if you really enjoy it. The hobby is very expensive, an average sized army costing in between 300 to 500 dollars depending on your army. But it is also very rewarding. The time you spend assembling, converting, and painting your army is very enjoyable, and in my opinion, the game is too. If you live in a community that has a fair amount of players, and you are willing on spending a lot of your money, then I highly recommend starting a Warhammer 40000 army.
Points values in Warhammer 40,000 are used to determine how effective a particulat miniature is on the field of battle. These points are used to determine the total size of the army, usually limited to values like 500, 1000, 1500, 1600, 2000, 2500 etc. depending on the size of the game being played. Troop units range in value from 4 to 20 points, tanks between 50 and 250, special characters 100 and more.
