I have a suggestions for this great engine… - Factions System for classes and NPCs; Allows for a user can choose which race is WoW style either Orc or Human, Elf. - Mission System; Although the event exists, could be used for other things, because it is complicated and rather simple to do missions with this system, however the system is more advanced missions. - Guilds System; Lack this system - Top Ranking System; You could add a system of rankings for high level users - Debuff Spells; With this system could use curse spells. Please be the best engine of history if he were to have all that. PD. Sorry my bad english.
