XOLODNIK  Missed my edit window but just wanted to elaborate on the differences between VO and EvE and point out that EvE is listed on MacUpdate as "Adventure" but Vendetta Online is listed as "Action" which sums up the differences in a nice, crunchy nutshell.

XOLODNIK  I've been playing Vendetta Online for about half a year now and plan to continue to subscribe for the foreseeable future. While not perfect with some key features still in development, I find VO captures the essence of space combat very well - even when using my joystick and after from many years of playing flight sims, VO transcends the "planes in space" feeling with which most other games in the space combat genre leave me; VO has done this by finding a good balance twixt realism and gameplay with their oddly tweaked 3-D physics model.

Other pluses to the game are: The client is native has been very stable for me even though I don't have the most up to date Mac. The network performance is rock solid making the PvP fun and satisfying. The community is generally supportive and is directly engaged in making VO a better game with publicly available customizations via skins, plugins, and even missions. Built-in voice chat via TeamSpeak, too.

Comparisons to the Escape Velocity series are valid as are those to earlier games in the genre like Elite and Freelancer with the caveat that VO is primarily a multi-player FPS in space with RPG trappings. However, future plans indicate that VO is evolving toward a more complex and dynamic economy which will provide for a richer and more interesting backdrop to the PvP action with more traditional RPG elements like trading, crafting, and mining getting more attention. (As for EvE, I find that the differences in gameplay completely outweigh the similarities which are, after all, common to most games in the same genre.)

Overall, a fun game if you're looking for a space-based MMO with solid PvP.
