In Gothic, you won't be constantly ganked, and then have messages like "Haha, noob and lol!" posted in the chat.

Yes, that's the main difference. It allows the escapist to be angry at a non-real monster that killed them, and not feel ashamed in front of another person for their weakness and lack of skill. On the other hand, that's the essence of an MMORPG; that's what people play it for – trash talk and bragging. Not for grinding skills like in TES (at least Gothic has a story and characters, although the core remains the same).

No. You're just used to seeing only the bad in everything, and that's what you saw in the game – the worst aspects, and you exaggerated them.

If you had exaggerated them, you wouldn't be torturing yourself with negativity; you would have just dropped the game, like you do with games you clearly don't like. But I played it through completely, on my second try.
Also, "seeing the bad," "worst aspects" – I just said that it's a single-player MMORPG. For schoolkid haters, of course, who, at any mention of an MMORPG, immediately dismiss it with their very important and original opinion "MMOs are garbage, I don't need them!", this is probably equivalent to the worst aspects. But not for me. Don't get so worked up, calm down.

And in Gothic, it's interesting even on low difficulty. Actually, it's even more interesting on low difficulty.
At the beginning, it's very interesting to take down a pack of wolves with a rusty two-handed sword without any skills.

No, it's NOT interesting. That's why I deleted the game from my hard drive after an hour of suffering and struggling with the controls the first time. It becomes interesting in the middle, when you no longer die from two hits and can move three meters off the road, but there's still enough challenge in the game world.

And there's no need to talk about the hardships of reaching level ten. In any online game, on any official server, it won't take "a very long time."
I don't know about D&D Online, whether it has only twenty levels, but in the others, it's quick.
In Lineage, quests are useless; they give too little experience compared to simply grinding mobs. It's a pity, the tedious leveling is the main argument against playing this Korean grind-fest; otherwise, it's very engaging with its free PvP.
