Yep, I want to know which RPGs do you think are the" top 5" of the worst RPGs.
My list:

1. Gothic
2. Gothic 2
3. Gothic 3
4. Risen
5. Divine Divinity

1) Baldur's Gate Siege of Dragonspear
2) Baldur's Gate Enhanced Edition
3) Baldur's Gate 2 Enhanced Edition
4) Icewind Dale Enhanced Edition
5) Oblivion

Ordered.

Explain the story and gameplay reasons as to why.

From what I've read, Sacred 3 isn't worthy of being spelled with the any of the letters in the set {a,r,e,c,d,S}

Risen 2
Risen 3 (Rubbish plot, annoying characters)
Lionheart: Legacy of the Crusader
Two Worlds
Two Worlds 2

I usually don't dedicate enough time to bad RPGs to determine which are the worst of the worst. :P

But of those I tried, Ravensword: Shadowlands seemed quite shitty, and of those I actually played through, I liked Evoland the least (pretty unimaginative and boring, less humor than the average RPG Maker game). But I strongly disliked the official campaigns of Neverwinter Nights and Icewind Dale, too. Such tedium, such lack of interesting characters and plot. Two Worlds seemed terrible at first, so it would have been a fitting candidate for such a list, but I found out it can actually be fun to play it.

Huh. I'd like to answer, but atm I can't think of any.

Two Worlds grew on me to where I love it.

I haven't gotten very far into Divine Divinity but I dig it.

I don't think I have any games that I would classify as "worst."

edit: after a moment's pondering, although I have mad nostalgia for a lot of the older D&D games, they seem so clunky now that it's hard to get into them.

Beyond divinity stands out in my mind atm. I wanted to like that damn game so bad.

1) Fallout 4
2) Fallout 3
3) Skyrim
4) Oblivion
5) Dragon Age Inquisition

So terrible they are barely 'rrr pee gees'

Brave topic and brave list, that may go to some conflicts.
There is no RPG game if we are talking about big popular titles (especially on GOG), that I can say are very bad.
There are some things that cause that I will not give a chance to some RPG titles, even if overall gameplay is good.

I personally do not like:
- japan style RPGs
- too flashy, too comics like, too colorful or too kiddy graphics
- all diablo clones

But, I am still glad that such titles are comming out.
Everyone have different likes and dislikes, so that would be very bad if titles which you do not like would never exist, so their fans would never get a chance to meet their favorite games.

Exactly. I never liked the Gothic games, I didn't like Two Worlds or Risen either, but I have not really spent enough time with any of those to give fairly such a critical opinion. I don't think they were that bad honestly, just not my kind of games. Maybe Dragon Age 2, that one I really think sucks balls.

Also, pretty much every MMO that calls itself an RPG should get an "honorary" mention on that list.

I, again, don't really like making lists, but I would actually say that Final Fantasy 7 is one of the worst RPGs I have ever played.

Dungeon Siege

Now I can't think of anything else bad, it overshadows all.

If we're talking GOG games, for me, Driftmoon would be one of them.
I've never played an RPG with conversations that boring before. Blah blah blah, yada yada yada, till I was about to shout, c'mon shut the f.. up and go on! First time an RPG almost made me angry because of lackluster NPC spiel.
