I am a bit upset that Studio is being dropped on XP but the client can live. Don't get me wrong I am (and I bet a market of others clinging to XP) are grateful for you guys extending the client life time but this means those users won't be able to make a game or even play in studio.
Another thing is if studio just blocks updating itself on XP it can create weird issues. I experienced one before with an older version of studio, It updated and my whole game corrupted. The second time my CSG got corrupted.
As @Wsly mentioned
'fans from the Philippines tweet me pictures of them playing the game'
If they got inspired to then try to create a game in studio, they can't. Just seems a little sloppy and a bit misshaped really, it's like having Sweet without the Sour, the onion without the ring, the ying but no yang.
