In regards to the single player, or the thought of a stand alone game for all I care.
- Make the armor and upgrades you purchase persistent.
- Have a separate lvl system for single player so that you can progress and just scale the AI for once you hit lvl 20 and go up to say 100.
- Add more random loot etc drops
- Make lvling in the single player separate and it takes a long time apposed to the reg where an hour or less is all you need to hit lvl 20.
Having persistent items / gear and constantly lvling higher would be amazing. It would be nice to progress then come back and keep getting ober gear and better skills. Perhaps even having an advanced spell tree for SP would be very nice as well.
If such a game, addon etc was made I would be all over it, too bad it was not part of the package. Bottom line if they do not make such an addon etc it would be such a shame to waste such cool characters / spells / environment etc.
Just a gob of my brains thoughts…
