PC building simulator

Obsessions cycle
around.  Latest one to be
revived is this game.

Ben gets fixated on things very easily and struggles to shake the idea of something, it can be as simple as playing Minecraft or packing a suitcase or as unusual as imagining himself in Jamie Oliver's kitchen.  There's not a lot you can do when one has gripped him, just try to make it as smooth as possible in order to avoid meltdowns when things go wrong.  When it's a game he doesn't really have the skills to play it can be problematic, if we (preventatively) take things away that causes a scene so we have to distract and sooth as much as possible and just hope for the best.  He's currently back into PC Building Simulator which frankly is glitchy and he can't follow the instructions but he can't seem to stop turning it on and having a go.  I've already averted two crises today, I do feel for him but it's wearing.  Anyway, he also wants to play at packing a suitcase which will inevitably make a mess :-/ but at least it's not on the computer! 
Happy Sunday all!
