Hey, this is a "Units" modification, it suits all game types so could be of interest to many of you fellow game owners.
User's can buy "Units", they can be what ever you want, I.E: 'Tanks','Boats','Horses', Anything that fits your game theme.
User's can then battle others with there units, depending on the power/speed/defence they win/lose in a very nice attack system.
Here are some screen-shots to show you the modification as I'm not a very good talker :L

http://img638.imageshack.us/img638/84/stafftrain.pngJust some information on the "Training" side of things...
Staff can create 'courses', you can pick name/description/price/Type/% increase in stats.
So for instance if I had a "Tank" as a Unit I could create a course with "Tank" as the Unit type, Upon completion the users "Tank" unit will be upgraded depending on the % set.
The battle has a win/lose/stalemate system.
I offer full support on this modification, there will be upgrades both free and paid, I'll throw a few ideas out there...
1) Marching time, It takes time to march to the other users "Battle Ground".
2) Being able to appoint a "General" which in return boosts units stat's depending on it's own.
You could use this as a complete replacement to the original attack system or run it side by side, your choice.

If you'd like to purchase please PM me the URL that will be used and the email you'd like the mod to be sent to, I'll then send my paypal address and upon payment I'll send the mod out.

I think that's it, any questions please let me know.
