I think that makin the game too realistick will take away the fun in rpgs
Quick! Examples of RPGs that have been ruined by too much realism! Mount&Blade? Thats pretty realistic right? That game can't be fun, right? Wrong.
Edit: The Unreal World? The game with starvation, freezing to death, deadly diseases, different damage types including blunt, slashing and piercing, extremely precise armor system, ability to rip your own clothes to make bandages for first aid, the player being cannon fodder for the bears instead of vice versa, drowning in any small bond without swimming skill, seasonal change in weather and foraging, shelter building, frustrating fishing and hunting when you can actually fail to catch anything as in real life, ability to dig or build traps for wildlife, crafting weapons, rafts, tools, even houses... and millions of other things I just can't write down. Plus no saving. That game SURE can't be fun, right? Wrong.
