Micro-transactions in games

Or paying real money to buy in game items–how often do you engage in such transactions? I’ve personally never purchased any in game items this way. The closest I’ve come to it was to buy a DLC pack for Tales of Vesperia when it came out about 6 years ago. I’m not particularly a fan of the model, but it does have the interesting side effect of stopping a gaming addiction in its tracks. I find that certain puzzle and strategy games have addictive mechanics, and it’s just a matter of a short time before the game tries to convince you to make micro-transactions to keep playing. At that time, it gives you a choice to pay to continue playing or requires you to wait so that your lives or energy units or what have you can have some time to replenish.
