I really loved Astérix & Obélix comics, so being able to play this with my brother in co-op mode really brought me joy. The game spanning over Galia, Brittania (including Rugby), Greece (including the Olympics)... really brought the comics to life. Being a platformer and a side-scroller brawler really showed its charm.
I'd really like to see this game re-released on GOG and be able to play it co-op again.
(Note: the game might be improperly tagged, with 1995 being a GBA game, and this one actually being released in 1996 on DOS, SNES, and Windows, with a different cover.)
