A few days ago I submitted a game here, newgrounds exclusively. It have frustrating hard-to-learn controls, and very steep difficulty increase. I thought adding some medals will increase it's popularity (:D), so I enchanted it with the NG API system, added medals, but didn't bothered adding advertisement, because I know it wouldn't get that popular.
After the few hours of the under judgement process, I wasn't surprised, it received an excepted low score. Checked back a few times that day, the low score remained, visitors were around ~700.
Here comes the interesting part: (four days later - today) I thougth i'll check the views again. 800+, not a great surprise. Then I checked the api page's views (it counts how many times the game started running online). Shocking number: 228,267 all-time views, 51,021 just today. Woah.. it might be a bug, I thougth. After a few minutes of googling I found the source of views. There is a spanish, and a chinese site who runs my game (put their advertisement before it - of course). Even the description were translated, they did it well, I liked it. The game recieved an approximately hih score there, and also made the #2nd place in action category.
Let's see. Good for players, they played a good game (i hope :P). Good for those sites, they earn money from ads, and 200k views. Good for Newgrounds, I placed a link for the page, it redirects people here. And last, it feels good for me that people play my game.
The funny thing is that if I put the ads in the game, i would've stucked with the 900 views.
Great dilemma: should I put ads in my further games and try to run 'em up by myself, or just write games and get satishfied with it...
