r. I think it's harder to have 20-40 dedicated games and you'll always find that one person that would say wow great collection but why don't you own "this" game in your collection... etc.
No kidding. I just found myself on that side of the hobby. On count the other day it turns out that including new projects I have 25 machines.... 25.... No, I don't have Galaga. No, I don't have defender... Yes I have Ms. Pacman.
Just a word of caution for all you "I could never find a place for dedicated" people. I've seen you have garages and sometimes, You can't pass up a deal. I was in the exact same position 12 years ago when I started. Thrift store find. Zaxxon. I never even played Zaxxon until that day (I was a galaga man...well small child...) but "dude,come on, $80... Including delivery." ...I had the money. I always wanted an arcade machine growing up. But where the hell would I even put it?
Of course then I was looking to repair it. Then I mame'd it. Which I might add used to be a problem you couldn't just throw money at. Dos. Advmame. VGA breakout cable. hacking gamepads. Staring at the PC2JAMMA page for hours on end ...eventually they came out with ArcadeOS and ipac and those were real game changers. Then I was on the look out for a Street Fighter (to cover all my horizontal bases) but we're talking about taking the hobby in to the thousands back then and I didn't have the skills to build my own it'd be even more expensive.
Somehow, it became 25. I'd say 20 of which are single purpose. I don't know how it happened but I can't picture my life without half of them. It's a mental illness but you'll find room. Bargaining with your Girlfriend, Wife, Boyfriend, Husband... Hell even taking some to your parents. You will find a way... And you'll help your friend build a mame and he'll go to the auction, too.
Even when I mame I'd rather have dedicated original controls and monitor. I can't just hang a giant everything panel off a 25" standup with a 20" tv in it. So even as Mamer...
This is for Racing. This is for Pinball. This is for 4 player games like Gauntlet and X-Men. This is for fighting... it's a Japanese Candy Cabinet. This is for Shmups.
I have a lot of classics: Donkey Kong, Ms. Pac, Tron, Space Invaders, Zaxxon, Missile Command Cocktail... Most need some work... I'll admit I'm neglecting them for my newer shiny multi-game setups because the old machines are more challenging and I don't have the time or space to work on them until I move.
Oh yeah that's another thing when you start to buy them. HOW TO MOVE when you need to move becomes a concern you never thought of. Before I started collecting, I could never understand the two car garage. I mean I got it. Park inside, take in groceries, etc., etc. but the modern car doesn't last as many years as the paint you're trying to protect by parking inside.
I like mame. I get mame. I on the other hand have a need for a room to power on. I have the need of the background experience. Friends all around me trying new things and breaking old records. I didn't need an arcade machine. I needed an arcade. Somehow, I did it.
Single cabs? I just feel like the people who can just eat one chip are show-offs. Also, they never stop eating that chip. Constantly striving to find the right mix of salt and vinegar. oh hell did you just add gravy? ...then grabbing another chip and starting over.
So back to the original point: Dedicated. Given space, time and money, there is no better way. Mame is because you have to. It's impractical to have Ms. Pacman AND Tron AND Space Invaders AND Donkey Kong... Unless you really want to.
