One to refer to the game as "beta" really shows a missunderstanding of "beta" and the software industry in general. "Beta" really has many more problems than this game did. Balance issues do not constitute the sort of problems that would keep a game as beta. Typically it deals with making sure a program (in this case a game) is "platform independant" or doesn't crash on as many platforms as are supported, major AI bugs(not weak AI), or that the engine functions as intended. As far as I can tell these problems do not exist with one exception: I have noticed an apparant memeory leak pertaining to archers. I still play with a few freinds of mine and I recomend this game to other stategy players as I can.
-To qualify my statments I'd like to say that I work in QA (so I get paid to find problems in software) and have been involved in sending projects back to coders as "not ready for release" multiple times. I'm also only 20 years old.-

Two not only do all programs past a variation of "print "Hello World" have problems (and even that case may be debateable). OH WELL. It is our job as users to responsibly report problems in as much detail and reason as we can. I have seen many game communities where nobody does ANYTHING but scream and complain about vague problems. While I don't think this is a particularly bad case (there are a not so small number of people who contribute), I also don't think as a community we have done perfectly. I don't have enough time to narrow down my observed problems and report specifics. I don't doubt there are a few others.

Third truly capable modding is extremely difficult until an SDK if released (note : I may have missed this).

I have seen alot of people complaining "the game is too fast" citing STW or MTW. This is unfounded as RTW seems to be a TOTALY different game as far as many factors go, speed being one of those.

Now I don't know what's going on in the MTW/STW world but... If you don't like RTW and prefer STW/MTW start or get involved in a community balance and upkeep project. Don't scream and complain about fundamental pieces of a game if there are games out there that have the features that you want play those and quit complaining about the ones that don't.
