i haven't played the game for like 25 years, i just remember the infinite flight stood out at the end.

I actually do remember playing those books as a kid. Of note, there's a weapon you get in the second book that is overpowered, to the point where, late in the series, the author started putting checks to limit its use.

I would argue that:
1. It's an action game, not an RPG (even if it does share many elements with RPGs).
2. It does have a growth system, even if the enemies scale with you. (Also, if you know what you're doing, it's possible to get powerful without leveling up, which breaks the game; Final Fantasy 8, to my understanding, has a similar issue.)

This game (which I have played, by the way) does have a growth system; you get XP and level up just like in most other RPGs.

Well, your definition of RPG itself IS quite debatable. Many would argue that it's an action game, not an RPG. So the answer to your initial request is no by definition. However, if you are into action games with exploration streak, try System Shock, Tek Wars and (I think) Hexen.

Btw, that's also debatable. Full Throttle, Blade Runner, Curse of Monkey Island, Gemini Rue and Dreamfall: TLJ have combat, but most people consider them pure adventure genre, since it doesn't happen often.

There is a difference between having combat and having a battle system. A battle system is, in a sense, a set of rules that governs all combat and produces an outcome. These rules can be things like "a character dies when HP is reduced to 0", "damage is equal to the attacker's ATK minus the defender's DEF, plus a random number between 7 and 13", "casting a spell uses up MP, and a character who lacks the MP can't cast the spell".

In a pure adventure game, you don't have such a unified set of rules and mechanics for combat. Instead, you might have a dragon that will instantly kill you if you happen not to have a certain item, and who can be killed by throwing a spear at it (but that same spear might not work against a sphinx found elsewhere in the game, for example). This basically makes each fight a (adventure-style) puzzle rather than a test of the player's or character's abilities. (Combat can still be complex; you could even have there be a big dialog tree, and at the end of every branch the script either gives you a game over or awards you victory.)

It's "she", not "he" (assuming you are referring to me); did you neglect to check my forum title?

some people consider zelda games like rpg so you can try any legend of zelda (except zelda 2 adventure of link) or some zelda clones. I.E if I remember well, Alundra doesn't have experience points.

Well as somebody said before, you need to provide ur definition of rpg but seems like you enjoy RPG elements but you want to remove experience points and, maybe the grind... I know.. sometimes it feels like cheeting, I don't like grind so I usually just take the minim experience possible (then the battles extends to 1 hs or 2 ^^)

Of course. Too many joke titles to ever take them seriously. Neglect to notice i didn't bother creating one for myself? Plus, rules of the net: it's either a boy or a G.I.R.L.
When games are too grindy, usually either get an EXP hack, find a cheap method to grind, or straight up do something to make it better. Honestly, does anyone 100% legit, no grinding tricks, no hacks, whatever get all skills in a TES game to 100? I doubt it.

True, he had a problem balancing things for the rest of the series. That's why I made up a new set of rules for many aspects, including weapons, which IMO made the series more enjoyable. : )

I hurt myself rolling my eyes so hard.

I know the difference betwen puzzles and battle system. And all mentioned games HAVE battle system - one that covers all combat encounters in a game. Combat in those is not a puzzle-like.
