False. Evidence: me. Most hardcore RPGs expect you to read a big ass manual and get acquaintanced with all mechanics as if you had been playing the game for weeks. Sorry, but I'm not gonna go through the hassle of reading the manual just to find the game simply isn't fun. That's what made Bethesda's RPGs so popular. It takes a matter of 1 hour, maybe? of starting the game and knowing whether you like it or not, and you don't even have to read a manual because it is all very intuitive. Does it lack depth? Of course it does, because what could have been a "tutorial dungeon" ends up being "your average dungeon".
Maybe a lot of people here are retarded, but there's a reason, like I mentioned, you aren't taught advanced math in first grade. You are taught the basics, and with every passing year your knowledge of math gets deeper. After a certain threshold, you stop "learning" math and you start "memorizing" math, which is why the average human being of 30 years who doesn't rely on advanced math to make a living has already forgot most of the "complex" mathematic formulas and so on.
