Im pretty sure his post said 30 or 35 not 40. I could care less.
I ll level to 50 as long as they put some 1000hp enemies that could down my walking Uber tank. lol
Vanilla Game then Old World Blues Trait = 30
Vanilla Game, Dead Money then Old World Blues Trait = 35
Vanilla Game, Dead Money, Honest Hearts, then Old World Blues Trait = 40
Again, this is dependent on what DLC's one has on an on-going save, not a new save. New save can be limited to 30 once Old World Blues is out, regardless of other DLC's.
Thats about 6.25 million xp more than you should get what a coincidence .
You really aren't getting my point.
It's taken me about 100 hours to get close to 250k XP, if you factor in just the XP requirement increase and nothing else. Therefore, it would take me about 2500 hours to get said 6.25 million XP. The amount of effort given to reach that point, and this is purely hypothetical based on your over-exaggerated #, would equate to nearly 100 + days of straight playing. If you factor in 8 hours of sleep, on average, that would be 133 + days.
Basically, you're underestimating how much time will be needed just from raising the XP needed.
It can be used as a really effective tool to control character progress if given a decent rate.
