I think the (re)advent of demos has been an amazing boon for the industry that it forgot. Whether simplified full games or up-to-a-point full releases, it’s great to give things a try before you buy. Demos were huge in the 90s, and then capitalism thought it knew better.
I, for one, have bought more games this year in part due to the demos, whereas I used to demure to frugality and concern over refund policies.
