I have WL1,3 an 4 but i beat all of them. I played this a long time ago (first WL game i played) at friends house an i wanted a copy but gamestore didn't have copy of game at the time but they had wario land 3 so i got it (wario land 4 and the GBA didn't come out yet) then when gba an WL4 came out i got that but my friend didn't manage to get a GBA but got WL2 (luckily) an i played an beat it an thats how i beat all WL games. I played super mario land but not the 2nd one but i didn't really like it (its just me thats all). an a few days ago i got this game at gamestore! u should get it too cuz it leaves off after marioland 2 (i know the plot from end of SML2-WL4) ill explain the  story
