The last week of the round-up is one I've been fearing since the start of the whole process. I knew I'd have to mention Regnum Online, and really didn't want to have to play it again to do so. So, what the hell - I didn't. I know this is a cop-out, but I'm just going to direct you to the previous entry regarding Regnum, and leave it at that.
OK, that's not entirely true. I downloaded Regnum again a few weeks ago, shortly after the start of the roundup. I I figured, naively, that the game might have improved somewhat in the months since I'd last tried it. It hadn't, so I uninstalled it within minutes.
That I can only stand to play the game for minutes at a time (this is, of course, not taking into account the many initial minutes of loading) really says something about Regnum's lack of, well, any redeeming qualities. I'm seeing myself type these words and feel as if I'm being harsh, but in my heart I know that it would only take a few minutes of playing Regnum again before I start to wonder why I'm being so easy on the game.
If you absolutely must play a free-to-play MMO on Linux and for some reason can't play any of the others previously mentioned in the roundup, well, even then I have a hard time recommending Regnum. Don't say I didn't warn you.
