Because WoW totally invented all of those things. :rolleyes:
I can guarantee you that every single CRPG to date that seems to have "unique" game mechanics like socketed items, mounts, etc was in Dungeons and Dragons long before.
No but I don′t think it′s any coincident I′ve seen just about any feature in WoW suggested here, and WoW was one of the first games I played that turned dragons from being intelligent into being mindless drones that are so weak you can kill 3 of them in 1 hit, and I′ve seen many suggestions here to let players "ride" dragons and to have "hundreds of dragons in epic battles!" clearly a sign that players with a certain mindset want to swat down dragons like flies.
I got nothing against unique game mechanics but just adding more stat slots through gems and runes is far from original and could just as easily be skipped by just making enchants stronger.
I′d rather see something more down to Nirn implemented, I don′t think runes(that are just magical by being written, but not cos they were enchanted) and gems (and then I mean gems that are just magical by nature, not cos they were enchanted or crafted with magic, basically enchanting them) have been around in the TES games I′ve played and there being a whole new brand of magical things everyone just supposedly missed noticing seems a bit off, but instead there could be for example re-forging of parts of armor/weapons possibly re-shaping the nature of a weapon entirely, like let′s look at how we could change a war-hammer.
1. You could add more metal to the head of the hammer possibly making swing speed slower but increasing damage(and weight) with heavier blows.
2. You could perhaps re-forge the hammer to have a hollow shaft(possibly making it break faster) making it lighter increasing swing speed but decreasing damage.
3. You could maybe add a small chain on the bottom of the hammer making it heavier but allowing you to quickly reel the hammer back into your hands if disarmed.
And so on and so on, the list can be endless. I don′t know many games that would allow re-forging (It′s different from WoW in the way that re-forging in that game just alters stats like stamina and such) a weapon like that, you could also do stuff with armor quite possibly.
