Well for us anyway
Loved risen due to how hard it was. Wow I was taken back. Oblivion sucked it was to easy and really everything was the same and way to dumbed down.
There is no comparison between Oblivion and Gothic/Risen. The former is entirely linear, there are no tangible consequences for your actions, you can be an Arch-Mage and head of the Warrior's Guild (you'd think that in an RPG that would exist as a contradiction) and that holds no sway to how other characters interact with you and... really, the game is just lifeless, soulless and a waste of time. The mechanics are vile, the class-system is pointless AND vile and it only JUST managed to be considered an RPG instead of some glorified pointless action-adventure game. I think the only reason it wasn't marketed as a pointless action-adventure game is because 99% of all action-adventure games are thoroughly immersive, enthralling and enjoyable.
Gothic and Risen are the only games where you are a part of the world instead of "above" it. You were no better (and in many ways inferior) to the average NPC and the rules that applied to them, applied to you. There was something magical about firing a steel blank, hammering it out, quenching it in water and sharpening it on a whetstone. There was something magical about collecting herbs, learning to create your own potions and finding an alchemy bench and have at it. There was just something magical about "seeing" yourself craft and going through the process.
There was something fiercely rewarding in going from nothing to specialising in your field (rogue, warrior, mage) and joining your respective guild by earning their trust and faith in you and rising in their ranks to be recognised as just that--a mage, a paladin or a mercenary. Comparing that degree of achievement, of class-influence to Oblivion where you could be a pit-fighting champion warrior mage while the average Joe on the street thinks you're some beggar waiting to steal their food stash is just pathetic.
And don't even get me started on the mindless, cheap and unpolished dialogue. There's nothing so humorous as a character talking about themselves in third person or suddenly forgetting that you'd spoken to them moments before.
Oblivion is a joke. Even die-hard fans of that series say the only time Oblivion even starts to become enjoyable is after it gets modded to hell.
But no, games like that have a following, they have fans and people that enjoy them and hey, to each their own. But a mindless, pointless world like that cannot be compared to a game that lives and breathes--a world whose perceptions you can shape by your decisions and a world in which you can thoroughly lose yourself.
I can't enjoy something like Oblivion and **** me, I've tried. I just can't enjoy it, it lacks everything that I crave and then some.
