Imagine if people could use out of context mechanics to get in-real-life "perks" in a manner similar to that of gaming microtransactions.
In some cases you might have people exclusively using it to get impossibly cool clothes. Probably nobody would be very upset by that. Or how about name/class/gender changes. I don't see many people complaining about that. Would probably make life a lot more comfortable for some people. Or what about increased bag space? So some people, because they bought that perk, they can carry 50% more groceries at a time. Not a big deal. I suppose those people would have an extreme advantage applying for menial warehouse and restocking positions, but that's not such an advantage that I think people would be very upset about it.
So what about people who buy in-real-life "mounts?" So there might be some people who get to live their entire lives with basically a free car. That would be a terrific advantage. Be the guy who has a porsche in high school, and never has to make car payments. That would be neat.
And then you might have cases where people get gold/xp bonuses. So, say...every class you take you take maybe you get a 20% "boost. So you only have to take four classes a week instead of 5, and you learn just as well. Or maybe regardless of what results you get on tests, you get a free 20% added. And for the gold boost, for your entire life, whatever job you work you get a 20% bonus to your salary. Make $40k/yr, you actually collect $48k. Make $50k/yr, you actually collect $60k.
That would be kind of neat.
Kind of a toss up which would be more powerful, the 20% gold/xp boost or the mount. On paper, for most people the permanent car/mount would probably be a bigger perk, but it depends. Sure, having a free $2200/mo lamborghini is going to be worth more dollars than a permanent 20% boost to salary for most people, but if you're making $50,000/yr, you might be better off taking the extra $10,000 and settling for something more practical. Still, I lean towards the car. Would depend on how you gamed it. Having and living in an $80,000 RV through college and your early 20s might be worth more, long-tern, than all the extra sex you'd have in the back of your lamborghini during high school. But is the sort of person who'd buy real-life microtransaction bonuses the sort of person who would live in an RV to save up to buy a house? Wouldn't they tend to be more the type for immediate gratification?
Of course, that's assuming you had to pick only one. The sort of person who uses microtransasctions probably wouldn't limit themselves to only one. So imagine having a porsche, and a lamborghini, and an $80,000 RV, starting in high school and that stay with you your entire life, plus a 20% boost to whatever salary you make, always. Plus the ability to switch your name, profession and gender any time you want to. Plus you can carry 50% more groceries. Can't forget that one.
What about server transfers? Not sure how to evaluate that one.
What about time speedups? Fast forward through your wait at the DMV at 10x speed.
What about games where you can outright buy gear? Those tend to be the microtransactions most frowned on in games, but I think it wouldn't seem as bad in real life. Bob down the street, POOF! has a brand new gaming computer and lawnmower that he didn't have to buy with in-real-life money. Not a big deal. Pets? So imagine every now and then you have a neighbor with a bengel tiger or elephant in his backyard. Interesting, but not real-life-breaking.
Overall I think people are unhappier about microtransactions in games than they would be if they applied to real life.
