I.m.o. it’s 50/50 for me.
If the dev’s will say “We’re gonna implement ships and planes” Then I say yessss! If they say it’s gonna unbalance the game, It won’t fit Train Fever. The maps are too small. It will make the game more unrealistic. It’s not on our ToDo list or whatever then I’m fine with that too.
For me it’s most important that if planes and ships are on the ToDo list, then I wish and hope the dev’s will do this as good as they can and make sure it will enrich Train Fever instead of demolish it. I trust the dev’s 100% to make this decision, which is not up to anybody in this thread.
