Well the final patch was released and it's much more stable now, if you have it or find it a a resonable price, you should definably check it out.
So I disagree with Asbjoern and it honestly sounds as if he has never played with the final patch, it's version 2.0 EU, here is a link.

It's a very creative attempt, which was forced out early by atari whom was in bankrupcty at the time, similar to what was done to G3.
I am sort of shock, why wouldn't BP qualify as a RPG?
Obviously just saying it isn't an RPG be bogus, so list an example of why it's not an RPG, please.
Here just to be fair I will start first here is a quick short list.
Multiple factions to gain and lose relations with, gaining gets you more quests with a faction while losing prevents quests.
Multiple endings, iirc but I usually play good, so I don't check all possible endings.
Stat increases through usage, like oblivion, which I honestly don't like much about it, but still Stats and progression is a RPG feature, afaik.
Multiple dialog choices and ways of completing quests.
I highly suggest if you play this to visit a RPGWatch forum member's [the nefarious Shadowmoses
] fan site, here.

For a couple Mods, most importantly the No Horns mod, it replaces the annoying and constant horn honking of the AI.
Also we are talking about a huge openworld RPG, in many respects it's a budget title, yet it can be extremely fun, if you like Shooter RPGs like Deus Ex.
