I don't think there's anything against it.
Ok, thank you
I have played both games many years ago and can't remember anything aside of some details.
One was on a console between PS2 or the old XBox, I can't remember. The game was about, I don't know, skateboards or rollerblades, not sure. Those people went through a city skating around, and they left a trail behind. The trail was like safety tape, if I remember well it was colored in stripes of yellow and black but I'm not sure.
The gameplay revolved around doing something with that tape skating around a realistic-looking city, and if I remember the physics were a bit floaty, probably they were hover skates or something... I'm not sure if it was a race or what.
I'm pretty sure that it wasn't Jet Set Radio, and I'm pretty sure I have played it multiplayer with a friend (only once).
I remembered of this game when I saw the trailer of the indie game "Hover: Revolt of Gamers" because I think it had a similar feeling.
The second game is way more difficult to find (it was emulated so I'm not even sure about the console).
It was a Zelda clone, or at least I think. It was reminiscent of A Link to the Past. I played very little of it, I remember that there were water streams with currents, and probably a puzzle maze based on it that transported you back at the start if you messed up. There where plants like in A Link to the Past, the map was structured as a grid of square tiles and each plant was one tile big, just like in ALTTP. There was a strange house that when I entered it, a sort of bossfight started, but it was strange. There were spinning sprites (I can't remember what they represented), I was convinced that it was impossible to defeat, whatever it was, and that it was a script to kick you out of the house (because if I remember, it didn't kill you but just kick you out). That "boss" thing was very early in the game, since I played it for a very short time.
I think it was for the Sega Genesis, but I was unable to find it even after a lot of research... I have found many lists of Zelda clones and I have never found this game. If not Genesis, maybe SNES, or... Neo Geo, is it possible that a Zelda-like game was on Neo-Geo? I think not but who knows.
I remember absolutely nothing of the story, I even think the game had little story/cutscenes and it just pushed you into the gameplay very early... (but maybe I just loaded some odd savestate? I think not, but I'm not sure).
