This myth of pc gaming requiring a uber expensive pc is seriously old. We have ancient consoles. So now for the most part the games are ancient also. The PC I used to play oblivion in 2007 could run Skyrim if I still owned it.
Mine still does, granted, it has had a couple of upgrades put in, but no more of those due to mobo limitations. It also plays every game released in the last 12 months.
Gamers do not need state of the art uber machines, so long as they actually do research and shop around, and learn what the computer tech all means...people who don't or won't do that are also the people who probably won't be able to do mods anyway, or trouble shoot the ones they install if they stuff up.
A lot of people on these forums, and it's primarily consolers, have no concept of what is involved in actually creating a decent mod. It's not like you are opening up your game inventory and swapping and changing things around. And when you actually install mods, some don't work with others, some are just cr*p, some don't start up, some crash, some cause weird effects...for instance, I have one that causes a crash to desktop if I select to return to the main game menu, and that is inconvenient at best.
It all sounds great when you read about it, or see videos etc, but the reality is that on the whole, it's not much.
