Spirits of Aldea
Savage Land RPG
Triumph (FaceBook application).
Travian (Strategy Game)
With the exception of the last two, the rest are awfully similar. I suspect there might be an open PHP source with the codes for them. If anyone knows about it, im very interested, as I am learning programing =)
Moreover, if you register for the first one, i will be very thankful, as I get points for invitation ^^
Theyre pretty simple games, and entertaining... Nice community with people from all around the world.
Hope you enjoy
If you know of other titles, let me know =)
