note that the original had no smaller island connected by two bridges, a detail which Garenas version inherited from PlayerUnknowns.
Battle Royale had such an influence on PUBG up to the point that the devs made a special skin for the homage:

Also note that there were some other rarely mentioned games that contributed to the conception of the battle royale genre. The Hunger Games Minecraft mod was the first I’ve seen the concept actually materialized in a video game.
Also note that last man standing with shrinking play zone was the multiplayer experience of the Bomberman game series, going back as far as 1983, but the japanese battle royal novel may have been inspired more by other "winner takes all" or "last survivor" patterns in popular culture and games that are far older. (wrestling and boxing, to be precise which included more "multiplayer" in the past than today). I wonder where the novel took the "forbidden zones" idea from, that became PUBGs "bombardment zones"
So a classic text adventure style interface and map, but you and the bots all started at random locations and have to go around searching for weapons & armour and trying to survive against each other to be the last one standing. Didn't have the concept of a shrinking playzone but was absolutely a Battle Royale.
Really enjoyed that one back in the day, and would often play while listening to the 'Unknown Girl' mod that was on the same disk. The Amiga had proper pre-emptive multitasking after all :-)
I don't think copyright applies unless code was actually copied. But IANAL.
