I usually have a hard rule about MTX in cases where it’s a question of keeping the lights on for always active services.
I’m mostly fine with it in a game like Helldivers 2 because realistically it’s taking the place of an MMO monthly subscription while being optionally gridded for and costing less.
Previously if you didn’t have the $14.99 a month then you could get bent and just not play. A lot of MMOs worked on this same model for an always active online game and even had an initial upfront cost in many cases.
Realistically this is taking the place of what would previously be a subscription for an always online service. I know this is going to be an agree to disagree case but I would much rather a MT based strategy than having to pay 15/ month.
On top of that if there is a warbond I’m not interested in (which at some point is probably going to happen) I can just opt out and not get it. You can’t exactly opt out of a required subscription.
I know people are going to say “Well you can’t compare this to an MMO Rocker!” to which I say look at both the rate of content delivery and the way the overall game is being shaped by active player and developer interaction.
To conclude sure, in the context of it being a single player / 4 player coop game micro transactions suck but in the context of getting charged 15 per month I’m fairly ok with it.
