When you see the title you'll probably say 'yes' right away, but then I think you didn't understand my completely (coz I wans't clear enough

). What I mean is something like this:
You can buy weapons, spells, abilities, etc. With buying an weapon I don't mean you change from an marine to an gholiath, but that you stay an marine and that your damage is saved virtually. When you encounter player2 you target him and you do damage and he targets you and he does damage to you, then you cast 'fire blast' but he resists it partly and he heals himself from 116 to 186 health, etc. etc. etc.
So this, and more, things are possible:
- Health is saved virtually
- Weapons, spells, abilities, etc. are stored virtually and can be used at the person you want at the time you want it
- Armor, magic shields, health upgrades, etc. are possible
- etc.
Simply said: An (close to) perfect battle system which combines good and fast gameplay together with the possiblity to have unlimited weapons, spells, armors, potions, etc.
Now my question is: IS THIS ALREADY MADE ??!
Because, I can I'm rather close to have done this. Well, to be honest, I did it

.
But I'm not sure if I said be happy as hell to be the inventor of extreemly good battle system... or that I'm just one of the many guys who found an new way to do something that has being done over a hundred times.
(Maybe I'll post an example map of what I mean, but maybe I'll wait until I have completed my Battle Arena map

)
