Maybe I was being a little over-defensive because of the way others commented without even trying (or downloading, or investigating) the game, and yes as a result I have support burnout. I'll give you the benefit of the doubt here and I hope you can accept my apologies.
Your first issue is actually quite valid, it seems with more players the setting for "serverupdateinterval" is too short to accommodate the lag between people geographically far away from the server. (I've since increased the default for that variable to 30, which I hope will alleviate the problem). Realise that we did get quite alot of good, decent regulars who are playing now (which was a little unexpected actually) and that the problem lies in latency and routing issues and not with the game itself.
Your second issue is not the map you are on but the mode you are playing in. Select something like "deathmatch" or "capture-the-flag" before hitting vote. Your fourth issue is a bit challenging, I'm Australian and you turned up while I was asleep, usually I'm the only one doing everything from coding to tech support (which, again, attributes to the burnout), and usually most of the people who have stuck around talked to me and learned first hand how to actually play the game (and once you get past that it's quite fun).
Your last issue is just a misconception (you can adjust the botscale variable to scale the number of players the map suggests). Note that bots auto-populate maps if you're actually playing a deathmatch game, you actually shouldn't need to interfere with it beyond altering botminskill/botmaxskill. There are some issues with the AI logic in certain setups too which have been addressed upstream (sometimes they would go insane and flip targets constantly every frame).
I don't feel "games are art" more that the aim of it is to have fun, not to over-analyse every little (and often irrelevant) detail, as some of the trolls here did. I bit off your head without thinking because of others here who have no heart. The people who have approached me directly and given friendly criticism or asked intelligent questions have often had their issue fixed within five minutes (or submit upstream to SVN for the patch). I even fixed the issues the trolls here posted, believe it or not.
Mistakes aside, this is all why I won't be participating in the Slashdot discussions from here on in; the nasty people had me become what I despise most about alot of projects - rude and condescending developers - and is actually the reason we started Blood Frontier in the first place. It's hard not to get jaded when there are so many ingrates, and in my experience it is best to avoid those types of people completely. I wasn't expecting everyone to love the project, but I was expecting I higher caliber in the responses from people who should know better. People like that, they're the reason the devs get like I did with you; again I apologise for catching you in the crossfire and appreciate your attempts to set things straight.
