I don’t do X-box, but I do play free games on the iPad.
Many of them offer in-app purchases. They are designed to pull you in slowly….. they offer you a package of boosts for 99p, but show you how much better value it would be to get the £1.99 one, then the £3.99 one, and so on.
I totted it up one month and realised I had spent over £100. I recognised that I was vulnerable to the intentionally addictive qualities of the game.
I went cold turkey. Still played the games, but didn’t do the in-app purchases. I relapsed once (about £50 worth) and then deleted the game which tempted me the most.
My point is - some people are more vulnerable than others to these tactics. Caught early enough, and if they recognise there’s a problem, it’s possible to escape.
But if they don’t see it as a problem, there is no hope. In that situation, you have to do what you have to do to defend yourself and your kids.
