Is this a question posed to decide how to spend the fortune you just secured winning the lottery, or after wacky uncle Ned left you everything. If so, the first thing you do is hire me as your gamer consultant. I don't come cheap, but I am thorough...
Time is my most precious commodity right now. No matter how much money I spent on gaming, I would require the time to take advantage of it. SO until we hit the 1,000,000 mark, we will have to ignore that fact, and go blow a wad of cash on making the most of it.
10k: buy a used Econoline Van and convert it into a mobile study / gear storage. No matter where I go to game, ALL my stuff is at hand. It would include a place to nap, a fridge, cabineted book storage, nice sound system, and a disco ball.
This would also make my wife happy as she would be rid of all my gaming gear.
100k: same as as 10k but a mid sized RV. This version would be fully networked, have a hefty computer, large screen TV, a custom gaming table, and well stocked full sized fridge. It is here I would spend all of my time, my wife would be widowed.
1M: With this I could really buy some time. Bills paid, invested properly, I could stretch this out enough to retire. Now I can achieve a proper balance in my life and game as my day job! All of my friends would still only be able to come out nights, so I would still have to tear myself away from my family a couple of nights a week, but she knew that when she married me.
