As an avid Maplestory player, can confirm. The end-game (post level 200, 5th job) actually forces "subtly" to spend money in enhances to your gear/equipment to increase your DPS (because almost all bosses are timed instanced, if you don't deal enough damage, you can stay like 20-30 minutes in the room and don't even deal half boss bar, Princess No, I'm looking at you, thanks to my guild for the carries), also the enhances (star force, cube, scrolls, hammers, flames, nebulites, etc.) are expensive as heck (to the level which you can easily spend 300€ for only a piece in gear) or straight p2w restrictred (you can buy from another players but is so expensive in-game money that is better using RL money) and also you add the fact that some of the enhancement systems are heavily RNG-based so... Well, overall is a good game for playing casually (the XP/ratio is so boosted that you can reach over LV100 in a day casually) and also the chacters are cute (let's not get started about how to change hair/face and colour, ugh...), also there's like 40+ playable classes Hero master race
