If you have enough set pieces, you can make an endless combination of modular sets. Keep your eyes open for little stuff you can add to a foamboard or wall piece to add some detail. Spend thousands on train buildings in order to convert a small fraction to set pieces. Go to Goodwill or the Salvation Army and buy dirty, smelly toys that have cool details. The only limit is your imagination and maybe your wife telling you to stop buying so much crap for your stupid toys. (My wife is actually very cool about my hobby. It is much cheaper than golf or heavy drinking.)

And I apologize for the small pictures. It was the only way I could make them small enough to post here. You can always use your zoom tool on them.
