I'am playing this game for a week now and my experience is far different from the game I played 10 years ago.
For me the main progression system and excitement in this game was hunting for the Card Upgrades. I loved playing with 3 of my friends specific maps to get specific card upgrades. The joy was in doing something (sometimes hard, sometime time consuming) and getting a reward for it. You had to play all maps multiple times and had the excitement for the loot after every game.
Now I am playing this game 1 hour a day FOR A WEEK, doing ONLY Bad Harvest and have my cards upraded on lvl 1 just by paying GOLD!
In my optinion this takes all the fun I had in this game away. You should get enough gold to be able to upgrate your cards, when you got the upgrading card you were farming for (and that should take some time, not a week!), but not to BUY the upgrading card.
For me it feels like there is nothing to work towards in this game. Farming gold and doing the most efficient map is not doing it for me, neither for my friends who played with me 10 years ago.
