Gobliiins was a adventure game as Yozy stated, you could die in the game and you could get softlocked if you took the wrong items or left the wrong items.
It was also mouse controlled.
Lost vikings was a platformer.
The biggest differences between those two games are
Adventure game/Platformer
Mouse controlled/Keyboard-controller
Goblins/Vikings
I personally did not enjoy gobliiins at all, i loved gobliins 2 and goblins 3 however.
I thing i did not notice until a couple of years ago was that Gobliiins has 3 “I”s because you control 3 goblins.
Gobliins 2 has Two because you control 2
And you guessed it, Goblins 3 has one “I” because you control 1
