One of the most divisive issues when you develop mobile games/apps is the issue of "how to get paid for it".
For a long time, people seemed to think the solution was to offer a 'free' (possibly ad-supported) version and a paid upgrade which removed the ads/added content accordingly.
That certainly worked for me - but technical issues (esp on Android) make that harder than you'd think to achieve and, in the end, I actually resorted to simply "living on the ads" - e.g. my games are free but there's no way to disable the ads, ever.
My logic was that people who are desperate to freeload, will always find a way to freeload and the one experiment I did with a 'free' and 'paid' app resulted in 8000 installs of the free one and ZERO purchases of the paid one (that's quite a division!).
Thing is, of course, there are many adblocking solutions out there - hell, some of the most popular Android ROMs have adblocking built-in! (an act akin to shipping pirated software IMO) - so it's not like it's hard to avoid them if you don't want to see them.
Of recent, tho, I've noticed (especially on iOS) that the 'free with ads' thing is strongly in decline - developers now seem to prefer a 'teasing' free demo which has iAPs to unlock the rest of the game. Whether this is due to the endless dilution of ad revenues, people's hostility to ads or another reason I've no idea but...
Where do you stand on the issue of ads in games?
Do they really bother you to the extent you'd not play a game where they appear?
Would you really pay money to remove them (I suspect many people say they will but few actually do - esp when there are 'free' alternatives?)
Have you ever sought-out mobile adblocking software yourself?
