I'm not too sure what you're asking, either. are you asking why I feel it is not realistic that different bars in different areas all have the exact same alcohol inventory?
Okay. Let me try to explain better.
One consideration is the reality of the subject. If you have more than one type of token, it's kind of like coupons... A merchants distributes a certain type of token which he is best suited to redeem. So a eatery that serves wine will not or cannot redeem beer tokens.
A bartender at a bar which only serves beer and wine would only sell beer and wine tokens. While a food shop that only has wine kegs would only sell wine tokens. Since the script on the keg itself determines which token is accepted, obviously the types of tokens accepted at any establishment would be determined by what types of kegs they have. That's absolutely reasonable, and I'm with you so far.
I think that would complicate the game somewhat...
This is where you begin to lose me. I suppose it would complicate the game somewhat, but I can't imagine how it could possibly complicate it enough to be a BAD thing, unless you're seriously underestimating the intelligence of the average Morrowind player.
and certainly complicate the overall use of tokens unless all liquor dealing establishments have all of the types of liquor, but that's not too realistic.
This is where I'm TOTALLY lost. We appear to already agree that some establishments would only offer certain types of beverages, so they would only sell (and accept) those types of tokens. Why would it simplify the complication for every alcohol dealing establishment to offer all three types of alcohol, and why would it aggravate the situation if they don't?
[edit] Also, it appears we've just passed that 200 post point. Let's put the discussion on hold until Gluby has a chance to start a new thread. Since it's his project I don't feel comfortable starting a new one myself.
