I guess it depends on how close he is to releasing JADE. It's probably not too important an issue since (I guess) there will only be a few places as densely populated as the "human city." But, who knows, there might be bigger ones...
Stat bonus is something like this.
[10] +0
[11] +0
[12] +1
[13] +1
[14] +2
[15] +2
[16] +3
[17] +3
[18] +4
[19] +4
[20] +5
This actually is talking about skill bonuses. For instance, assuming you made a walk silently check in Dungeons and Dragons. You rolled a 15 and your attribute was 16. You would get a bonus of +3, making your total roll 18 to see if you made it. I am assuming this is the case for Jade.
Yeah, well, I'd love it if all the orcs wouldn't attack everyone, including orcs, on sight. Sure, in ADOM ChAoS can drive everyone to try and kill you on sight but in JADE I'd find it nice to be able to visit different races' villages. (They should be different of course. Some cities might be in caves. Others might be concealed... whatever.)
A bit mad of me yes, especially since it seems work on it has ground to a halt again. However I wouldn't want TB getting bogged down with minor details involved in creating a releasable version when at this stage of design it's best to concentrate more on the general architecture of the program and over-arching features. In the long-run (and it will be a long run either way) we will have a better JADE if we let him do his own things before a playable version is released.
Early release = we can help more with bug reporting and things like that. I will not mind playing an extremely buggy and inbalanced game, I've done it many times before.
