Preferably for the PC, if at all possible.
(yes, I do already have Drakan:TAG, but my current hardware is far too wimpy to emulate it well; currently building a new system)
A few years ago - which is when I found out about Drakan:OOTF in the first place - I did also search for other such games, but alas, with nothing useful to show for my efforts.
Now, it's time for some critical panning:
Skyrim doesn't count - the dragons are not rideable at all in vanilla game, save in a single cutscene - and AFAIK even with the DLC it's... quite lacking in this regard.
Seems like this was not being considered at all during development, and then just tacked on for the DLC - crippled as it is, due to having to deal with engine and/or game design limitations.
I did play the DLC more or less to completion once. Had to turn the difficulty all the way down for the unavoidable dragon-riding fight towards the end, due to weird technical (???) issues - the interface appeared to be totally broken: all of my "dragon controlling" inputs did absolutely nothing; might have as well unplugged both mouse and keyboard for that fight, and it would've made no difference.
After that fiasco, I never tried it again - mostly because it didn't fit my overall playing style for that character; also shortly after that I had to put Skyrim away due to other, more pressing issues, and then didn't care much about returning to it before upgrading the (rather dated) hardware.
Divinity 2 (DKS) is the closest thing to Drakan which I have found so far.
A lot of wasted potential there, though - the main problems being:
1. The ground enemies disappear when changing into dragon form. Wait, what?????

When I first saw this mentioned in a review of the game, I was like "haha, no way that could actually be true - good joke, buddy!".
And then after many hours of playing, I was not amused to discover that it was, in fact, not a joke by the reviewer, but rather by the developers.

Also, even in the Developer's Cut version, to the best of my knowledge there is NO WAY to change this behavior at all, even with console commands.
2. Has a serious pacing issue with the plot, too - similar to the problem with, say, Jedi Knight II: Jedi Outcast.
Except it's actually much worse, due to problem (1) above - think JKII:JO but with Jedi powers only being usable on D.Jedi/Sith enemies, and not at all on any of the mooks.
3. Pulls a cheap trick to reuse parts of previous levels after getting the dragon form.
Feels like a massive budget cut happened halfway through development, preventing real new content from being created.
4. The fortresses are simply tedious to deal with (more evidence of budget cuts?), and problem (1) above makes it far worse than it otherwise would have been.
For me, this last issue in particular was the straw that finally broke the camel's back. Not far into the 2nd fortress, IIRC.
After uninstalling the game, I then read a Let's Play of it to see what had I missed out on. I regret nothing, really - or, at most, very little.
So yeah, Divinity 2: an excellent example of how poor design decisions can result in making a steaming turd out of even the most promising ingredients.
It does not cease to amaze me how such most fundamental things could be bungled up so thoroughly. By a large group of people, no less.
Drakan, despite preceding both of the above games by many years, and created in a different era of games altogether, still gets the idea of "fun" mostly right:
- Arokh is quite overpowered, even right from the start, yet you can't take him everywhere,
- fighting ground enemies from the air is mostly like shooting fish in a barrel - a lot of fun, as it should be,
- normally, that would quickly get old, for lack of any real challenge - but the game does a good job alternating the grilling of enemies with solo areas,
- no blatant level reuse or extensive backtracking,
- flying enemies don't have ridiculously bloated HP pools.
