Even though I do think cheaters pack is a dev thing, I also think they are going to sell credits. There is no reason for the design of career mode otherwise.
The entire career mode reeks of designing it to sell you the solution later. I know people who love flight sims are gonna be like nahhhhh. I’ve seen this play out way too many times. Might not even be credits but “boosters” for player “convenience”.
If this isn’t their plan I can’t fathom why they force players to spend 40 or more real life hours in the C172 with all the insanely brutal punishments the game has to offer, all of which affect one thing, credits.
