hi aizen
what kind of pet you meaning ? i like to see a good pet system like you can summon/recall it from item or from stable
pet can use skills and heals/buffs to help players to kill mobs
let me add this to the list:
1-auction - this will make selling item very easy and stop spamming selling item on chat
2-effects when die - this will save a lot of work on making die animation for every mobs
so you can use explode or suck to ground effect instead of animations
3-ladder system - look at video
4- dungeon under terrain- i build my dungeon but i can't enter to it! because the water collision cover all the map and there's no way to Exception some area
5- path transport - transport players in ship between islands
6- multiple xp/drops/golds
7- decals/tattos
8- spawn mob after mob killed
9- timed item / item change over time / use time when equipped
10- press shift to sprint
11-daily quest
12- reset password - email conformation
