Hello,
Retro RPG Online 2.5 is initially based off the BrowserQuest and later add Asky BrowserQuest Engines. The Devs broke up due to internal differences and departed on there own journeys. Anyway RRO is an attempt at re-creating a early SNES experience of Secret of Mana or Zelda and porting it to an online RPG scale.
Anyway the Map Game Engine is currently being developed and has a few bugs still which need to be ironed out. Basically it's designed to work with massive scale maps and load what is needed on the fly. It also will include collision and path-finding. Here is the Game Engine Demo:
Future Features will be a real-time attack system much like early SNES RPG Games. You will be able to dodge most Enemy attacks and power-up to do more devastating blows. It will also have higher player levels (possibly up to Lv200), and seperate skill levels that get more powerful as you use them. Players will be also be able to allocate points into attributes each level to better there Character.
The Monsters will have fixed level formulas and depending on the type will have modifiers which may make them faster or more deadly. The Quest system will initially be very basic, find items or kill monsters. The next major release I plan to make a plugin engine for more interesting and varied Quest gameplay. PvP will most likely be map-wide and we may also have a non-pvp Server and being able to load into either one. If you die in a map you will become a ghost and it will give you maybe 20 seconds or so to get away from where you died.
You will be also able to teleport to any player with there consent, and teleport to a safe house, where you can Buy items, Auction, Enchant Weapons, purchase looks, and turn in item quests. Special looks maybe become a subcription or pay-once thing, and also minor in-game benefits such as +25%-50%xp (still being decided).
Thats all I can think of for now, thanks and hope maybe to see some of you in Closed-Beta, and yes Closed Beta will have a wipe of characters at the end and maybe give a reward to early testers. Thanks for reading.
