It isn't a problem and you have a very good point as far as the "try before you buy" way of using it. That's a really good way of seeing if you like the DLCs.Why would be that a problem?
I could pay €5 and try all of them for a month.
If i like the DLC i may consider shelling out the cash required to buy the whole package. Or only the stuff that may interest me
If not, i can move on, saving a lot of cash.
I just think that if you subscribe long enough to have paid the equivalent or more than the cost of the DLCs, then you should get to keep them. That way, everyone wins.
As you said, you don't play PlanCo, so I don't know if you know about the way the game saves. Basically, if you open a park, blueprint of any file containing DLC that you don't own, you can play and build within it but you can't save your progress. So if you stop your subscription, you'll in effect, no longer be able to progress with anything you've built using the DLCs. And as some of us players have spent 100s, or in my case 1000s of hours in game, so losing all that work would be both unthinkable and unacceptable.
I'm not hating on this at all.
I have all the DLC s already. I've always supported Frontier and have been lucky enough to have met the devs and community teams many times. They're a really decent, lovely bunch.
I'm just trying to look at this objectively and think of how it could affect the players who go for this subscription further down the line.
