Depends. Do we count in-app purchases of apps I've modded or obtained pre-modded? Do we count the cost of films as one-off rentals/purchases, or do we count them as subscriptions?
If we consider games as buying one-off licences for them that I kept in perpetuity, it would be in the few hundreds, probably about £400.
If we include streaming, as a subscription service that I've used for the last decade roughly, then 10×12×£10 (assuming a tenner a month), we're looking at £1,200 saved for streaming.
However, at least 20-30 films have been downloaded by me personally, so assuming a cost of about a fiver per film (idk how much films go for these days), we're looking at another ~£700.
But also, we have to include ad-free YouTube as YT Premium. And even if we're to assume that YT Premium is anywhere close to the service I provide myself with, i.e downloading things I actually keep as digital files forever, it would still cost a lot. About 5 years of YT Premium would be (according to ChatGPT because I didn't want to research price increases), just over £800.
But I've also watched both Netflix and Disney+ exclusives, namely Squid Game and The Mandalorian, so I guess streaming would've been much more expensive?
Also, we have about a year of Spotify, which ChatGPT (easier to give more accurate estimates) claims is just over £140.
Adding to that, apparently the cost of Netflix over the same period is just over £1,500, so that changes the total.
So far, £3500, not counting in-app purchases in modded games. If we count that (which is ridiculous cuz I would never spend that much money on games, even if I was a liquid trillionaire (meaning having £1T cash)), we'd probably be looking at something in the hundreds of thousands if not millions.
