I got two words: Flappy Bird.
That should be enough. Let me elaborate though.
For such a simple and dare I say fugly game it has raked in tons of cash-money. There are other similar games that have also got massive amounts of downloads from Google Play...
Being that we operate in a market driven economy (mostly) it logically follows that the market decides what kind of games succeed - monetarily = get loads of that good cash-money.
That being said - a game being good is completely subjective. Simple games can be good, complex games can be bad. It doesn't matter much. What matters is...
good games don't always make tons of cash-money
bad games don't always make tons of cash-money
sometimes good games make tons of money
sometimes bad games make tons of money
For what I'm looking for is getting to make awesome games but I realize that I may have to make a few mediocre ones first to get the process down pat. And also I'm looking for a source of income to get me there. Money is what gives artists like everyone here the freedom to create what they want. (imagine how much more one can accomplish if one doesn't have to slave away ones precious hours to an employer [making that employer tons of money])
And it brings me great joy to create something.
