Okay another question of mine:

I am using a standard point cost system in my current game - a wargame. So each player buys the troops he wants to use in the battle before the game starts.

In a typical game each player has 1000 goldpieces (buy-points) to spend on troops, artefacts and equipment (just like in warhammer but one thousand is a suitable number.

all of the objects in my game are made of "Generation Points" that the designer can spend to buy attribute-levels and special powers. some roleplaying games allowed the player to generate his character using a point system just like mine. in my scenario the generation points are only for the game-designer (i want to be able to expand the game later on).

as a rough guide all of my units are made up from 12 to 70 points. so i am trying to assign a goldcost to any number of generation points or to find a suitable formula to calculate the total cost. right now i am using a triangular numbers aproach - but the numbers get very large (a 70 point unit costs 2485 gold according to the triangular number formula).

so any suggestions welcome. I can change everyhting except the number of generation points and the fact that I just want to use a steadily increasing point cost model instead of the standard 5-10-15-20-25-30-25-and-so-on stuff.

Thanks for the Info Emphyrio. I will try and play a bit with the formula you provided.

Basicly I used triangular numbers because I wanted the goldcost to rise curve like. Because a 20 point unit is much more powerful then 5x5 point units. The 5x5 get more attacks but thats relative because the 20 point unit has much more possibilities: it can access the higher skill levels and better skills in general.
