Cappable Train Stations, to actually make trains interesting again..
Oh, I can make trains more interesting, but you probably don't want that
*Laughs*
Keith, I've plenty of faith in both you and Chris to not turn Trains into randomly-pathing engines of insta-gib. They'd only need nerfing straight after they were released, anyway. Besides, I personally don't mind things that make the game more random, interesting, challenging, or all three at once. That, and having cappable Stations would definitely be a good reward/pain scenario. Like the thread says (Paraphrasing, not quoting here), "You'd gain some income, whilst at the same time be encouraging Trains to enter your territory. It's not win/win, it's balanced.".
Now, if those same Stations gave an income (Of whatever M/C per sec, or a variable lump-sum, depending on which train-type docked) AND gave a wave-multiplier too, that might be a tad much. Still, testing would find the proper balance, imo.
