One thing I've noticed in regards to modded consoles or flash carts, is that I end up having hundreds of games for a particular system, and the big problem with that for me, is that there is just TOO MUCH SELECTION. Too many options. Take the Saturn for example. I probably have like 200 or so Saturn games. Every time I go over to the shelf where they are, I normally decide to try a game I haven't really played with, just because it's there. Instead of getting deeper into one that I know I love. I call it the "Dip your toe in the Water Phenomenom". When you have hundreds of games for a particular system, often times, you end up dipping your toe into tons of different waters. Yet, you never get deep into the water on anything. Too much variety, and too many options can be a bad thing.
This is also true with actual legal, physical copies of games. Sure, I have some CD-R's, but I've also got tons of legit games as well. Tons of various systems, and tons of games. When you have too many damn options, then it's hard to really focus in on any one thing. I could never add another single game to my collection, and I would have enough games to keep me busy for 30 years, if not more.
Of course, on the flip side of the coin, I've also been in situations in which I only had a handful of games, and although I would get deeper into those games, sometimes it would get to the point where I just didn't feel like playing those damn games, but they were all I had. Almost like I would look at the games sitting there and get pissed off at them. Like... "I don't want to play you again, bitch!". So, it's kinda a damned if you do, damned if you don't scenario.
