What features do you miss in TTO, which later versions lack or which have been changed? Do you still play the original only from time to time, to remember "the good old days" or is there anything in particular keeping you faithful to the origins?
(I shouldn't be saying it in this section, but it might also help make a mod for the OpenTTD, to bring out the best of both worlds

)
Things I personally miss are aesthetic:
- company colors. Much better than the new ones screwing up my eyes.
- the old GUI - the window graphics. It took me some time to get used when I first saw TTD.
- So, here's this train full of illegal alcohol. I stamp here, and all the alcohol magically evaporates, leaving pure mineral water...
