I’ve always bought my games on steam or OFFICIAL key resellers (GMG) since I was an adult, but sometimes it has got really expensive.
Do you consider ‘cracked games’ safe for your PC, your data, and finally your privacy?
You should always support developers, but it’s not always possible.
If it’s a “trusted” source, as in a popular one, such as a certain link from a certain girl that is fit, yes.
Otherwise another option I’ve done for a while was buying cheap keys from greymarket type resellers, though for those I only did them from AAA publishers never putting their games on sale and on a second account (idea being you minimize risk and if something did turn out to be a stolen key, which was a problem for a while on those kinds of sites, a chargeback isn’t going to hurt a AAA publisher as much as an honest small published in house indie dev team).
