Give Me Your Best OpenTTD NewGRFs

I've finished my NewGRF that adds tea to OpenTTD. It's not publicly available yet, because I want to test it more and see if there's anything that should be tweaked.

Now I want to know which mods you all like! Specific vehicles, town names, scenarios, height maps, industries, etc. Anything that makes it fun to start earlier than 1900, or playing later than 2050? Anything that makes gameplay more interesting in general?

Tell me and you're in the running to win 10,000 points!
