Sorry, rynetory, I've got to agree with seesters. The costs in this game ARE too high, IMO. Some of the recipes may have a higher plate price as you level up, but then the cost to do just about anything skyrockets too. Instead of 250K - 300K coins, we're looking at 1M+
I'm at level 28 and there aren't really that many "higher profit" recipes available. PB balls at 6pts and the 2 cakes at 8 pts and ... well that's about it. The newest main recipe I've come across is only 5 pts (raspberry galette) and that's the same amount as the previous recipe for that appliance (creme brulee) but it costs $350K to unlock the new ingredients plus IIRK >$1M to unlock the recipe. So after saving and saving and waiting and waiting to open that new recipe, players wind up with something that's no better than the recipes they already have for the same appliance.
I thought the new short-term goals (the Marshmallow ones) might add a bit of fun, but that goal chain is growing tedious because it relies so heavily on one ingredient through all the goals. I thought BS2 would be a fun little game to play in my downtime, but it's kind of dull at the moment...just waiting around for ingredients to be dropped or available to buy after hours and hours, and then having only enough to able to make just 1-2 batches of homemade ingredients and THAT's only enough to maybe make only one recipe, when the current goal requires like 30 batches, and no real ability to earn more of the limited ingredient (since any chance to earn more requires recipes that use the same exact ingredient)
So, IMO the "value" does not get better as you go further in the game. In fact, the long wait times and cook times and high costs makes the game more tedious. I hope the designers take a look and reevaluate the value structure of the game to make it more interesting with the next update.
