Blue Mars. http://www.bluemars.com/ BM (what an unfortunate acronym!) has very high-tech underpinnings compared to SL. In theory at least, its visual appearance is superior. When I visited, I found the range of avatar customization to be much more limited than SL. BM features some interesting concepts. For example, one can have a designated private space, such as the inside of one’s home. People outside this space can’t see into it, in fact it does not exist at all in their version of reality. Moreover, there can be multiple “instances” of this space; a landlord could rent out the same apartment to several tenants, and each would have their “own” place, all at the same physical address. Object creation is done with offline third party programs, much as Mesh will be done in SL. Desmond Shang, the owner of the very successful Caledon estate in Second Life, has established two colonies on Blue Mars; one is a steampunk-themed area like Caledon, while the other is a less structured tropical island type of setting.
InWorldz. http://inworldz.com/ The best way I can describe InWorldz is that it’s Second Life, but four years ago. But that is misleading. IWz is a grid based on the OpenSim server software which is indeed derived from an earlier version of the Second Life server code. So technically speaking, it’s like an earlier version of SL. Apparently, a (really good) physics system has now been added, which removes one of my major complaints. Many of the newer features such as avatar physics and multiple clothing layers are not available. On my visits there, I have found things to be even less stable than SL, with frequent crashes when trying to fly long distances and cross region borders (this may have improved, I haven't been there in a year or so). However…IWz has a much different social “feel” than SL, or even SL-as-it-was. This is because most of the inhabitants of IWz are experienced Second Life residents, people who know how to behave in virtual reality. The hordes of griefers and rude people who throng the SL infohubs are simply not there. The technology is shaky, and financially speaking IWz is a “basement hobbyist” effort compared to the enormous Second Life Grid…but the people who live there are smart, polite, and intensely passionate and involved in making “their” world an attractive place.
OpenSim. http://opensimulator.org/wiki/Main_Page This isn’t one virtual world, but many. You can download OpenSim software for free and install it on your own computer, and create your very own private Second-Life-like virtual world. You can even link it to grids hosted by others in a sort of hyper-grid system. Travel between these grids is nowhere near as straightforward as teleporting to another sim. It’s much more like logging off one set of internet forums and logging onto another.
IMVU. http://www.imvu.com/ IMVU is really geared toward the teenagers. Content creation requires a premium account, and all virtual goods are subject to approval by the game’s managers. Sony, the owner of IMVU, gets a cut of all content sold. The world consists of linked “rooms”. You can go from one room to another in a process like SL teleporting, but there is no physical connection. Each “room” is its own mini-universe. While their ads entice you with slogans like “Dress Up for Grownups” and “Be Sexy”, IMVU does not permit any adult content.
Red Light District/Utherverse. http://www.redlightutherverse.com/ In direct contrast to IMVU, this virtual world is all about adult content. In fact, many of the things that make Second Life a “world” are not present here. The emphasis is on sex, not on living a well rounded virtual existence.
Eve Online. http://trial.eveonline.com/en/eveisreal.aspx More of a roleplaying game (like World of Warcraft, but in a science fiction type of shared universe rather than a fantasy-based one). Captain a starship, fight space battles. Develop strategies and tactics. Eve does not have 3D animated avatars, but the space graphics are gorgeous. There's a free trial, but it costs about $10.00 - $15.00 per month to play.
World of Warcraft. http://us.battle.net/wow/en/ Huge fantasy game. Free to play, up to level 20. Despite being games with rules and levels, rather than open ended virtual world platforms, both Eve Online and WoW are used by many for social networking purposes.
