When a person thinks about getting to level 50 in any game most think they have completed half a milestone
....uh, what?
What do all of you game fans of Skyrim think about the level cap?
No problem with it at all. Seems like a huge number of levels, actually.
...of course, "level caps" and numbers of levels don't really matter in and of themselves. The important thing is that the game itself (the challenges, combat, power levels, etc) are balanced around the levels that the game has.
Which is why I thought that the lv20 cap in Fallout 3 was good, and the increase to 30 in Broken Steel was bad - the game was designed and balanced around the powers you gained in those 20 levels. Adding another 10 on top of that (and all the stat gains, HP gains, perks) screwed everything up. (Now, I agree that the player reached the lv20 cap too quickly. But that's not the same thing as wanting more levels.)
Personally, I'm frequently mystified by the "want MOAR levels!" thing. It's all just a number and a framework. That number being able to get higher, doesn't necessarily make it better.
For instance - I can make basic Fallout 3
100 levels! DIvide the number of XP needed for each of the original levels by 5. Divide the number of HP you get each level by 5. And only give a perk every 5 levels. Voila! 100 levels! And it's absolutely no different than the 20 levels, statistically - the only different is you see a bigger number, and got to hear the "level up" noise 80 more times.
See how pointless that was?
