If the only way for me to get single player games is to buy a console, so be it.

It’s not though, that is a false dichotomy. Just because the major publishers are pushing trash because it’s profitable does not mean that single player games are impossible for cross platform.

Look at FromSoft, Bloodborne is made with the same engine as Dark Souls 3 which is available cross platform, same as Dark Souls 1 and 2, yet Bloodborne is exclusive because Sony is intentionally crafting a captive audience.

Both, your gripes with major publishers and console exclusivity, come from corporate putting sales above all else, yet you excuse one but not the other.

Exclusivity has nothing to do with viability
