If you have a "replacement" game for VMK, what is it?...
I don't think I will ever find any 1 game to replace all that VMK had for me. That said the following games are what I am currently playing or looking forward to playing once they are released.
Pirates of the Caribbean Online (and test also)
I played this a lot right after VMK closed. Really loved the sailing and ship battling aspect of it. However coming to the end of the quest lines, mastering sailing, and the lack of updates of interest to me has caused me to play a lot less now.
Wizard101 (and test when it is open)
I played this a lot as my interest in Pirates waned. Love the deck based, combat part of it. My interest waned a bit when I came to the temporary end of the story line, but the story has been expanded now. Really looking forward to the soon to be released housing (decorating the interiors and exteriors of prebuilt rooms and "castles") aspect of this game. This will add a social aspect to this game that has not been realized yet in other games I am playing.
Guild Wars (Phophecies campaign)
Really love this game as it takes me back to my past love of console based, sword/sorcery, RPGs. The best part for me is that a lot of it can be played solo using only computer generated henchmen. It also is a well established game, so if I need help there usually are others around to be asked.
Metaplace - closed beta for now with keys available
I have just started this game and see good potential in the building and socializing aspects of it. In this game you are given your "world" that can include up to 10 places. There are a lot of building possibilities in your world and you can also place "teleports" to other players worlds.
Free Realms beta coming
This is a game being built by Sony Online Entertainment (SOE). From the pictures and videos that have been released it looks rather amazing.
I tried Elf Island in early beta and it did not appeal to me much.
