YouTube has this thing now called YouTube Playables (great name as usual, guys; it's not a children's snack pack), that are basically in-app "Flash games"-style things that are just enough game to keep you watching ads.
The ones of these that aren't direct ripoffs of owned IP (very specifically Zuma) are barebones exercises in that bog-standard FTP addictive mobile gaming loop we all know and hate but also LOVE, minus the in-app purchases (for the time being). Like, shallow systems that are fun for exactly 30 minutes, then get stupidly hard so you'll pay to win, though you can't do that yet, so...kind of pointless.
...I still spent FOUR HOURS playing these, because they tapped into my primitive lizard brain's desire to try and master an utterly meaningless task and then feel undooly smug about it.
I didn't get any ads, because I'm a stooge that pays real money to Google every month for this, because once you go adless, you CANNOT go back. Which kind of negates the whole point of these, as addictive time-wasters that keep you glued to the platform and its commercials? But I already pay for YouTube and STILL got caught in these, so I suppose everything is going according to YouTube's plan either way, and I need meaningful human relationships.
But THAT isn't going to happen any time soon! So let me waste another evening on these by reviewing some crap garbage games for idiots that no one cares about, on Tumblr dot com!
