Always the easy way out for cheap gamers...
AS IF the games of this generation aren't RIDICULOUSLY easy and simple that even a 9 year old has no problem playing them. I would have loved to see a 9 year old play and understand Morrowind, heck, even Final Fantasy 3 or Secrets of Mana....
Anyways, to answer the questions, NO. They limited the game because once you hit level 20 anyways, you become incredibly over powered if you played the game right, and most ennemies, who do not scale with you, will completely cease to be a challenge. All this can be accomplished in under 100 hours, which for an RPG is not very big if you compared to others who can take THOUSANDS of hours to fully explore. The "creators" did a fine job of limiting people who would have just posted videos of themselves at level 500 on the internet and how they are Gods of the Wastelands had they NOT put a level cap on it.
So here's the deal, you have a very tough choice; deal with it, or don't play the game. But don't say other people scr*ed up, the only ones screwing up games are the people who want to bend it's rules and cheat with it, sorry.
