Well, completing the game in Origins can be easy if you have it on Easy mode
You're not limited to at most 9 useages per spell level and you level up much faster, unlike Normal mode
On Normal mode you probably won't get much higher in level than level 30, maybe 40 if you go nuts with the leveling.. on Easy mode you would be level 41 with the same amount of exp that gives level 30 on Normal, and level 54 with the same amount of exp that gives level 40 on Normal
But in any case.. if you beat Warmech on Origins, then I may be impressed
At least if you did it on Normal mode..
