I don't think a whole lot was really said about how precisely the stronghold will work....so I'm not going to make any assumptions. It says the stronghold will allow management of card troops and limit the number a player can deploy on offense. I'll have wait and see before making a personal judgement, but I do think the response to its announcement says a whole lot.
from a personal perspective only, if the stronghold does turn out to be a mechanism that applies peer pressure to purchase card troops in order to be competitive in war I will opt out of war. This isn't a threat. If there are enough players out there that would want such a feature and would enjoy the game more with it in the game, then it should be there. I would enjoy the game less, and may move on, but the game appealed to me for a long time. If it appeals to a different kind of player as it evolves, so be it.
I could be wrong but it seems most games start out as a relatively basic structure. If the game is successful then there is a period where a significant investment in the game is made, and during this period the classic model more or less remains while the people behind the game essentially redevelop it behind the scenes. This significant investment must be recouped, so with the eventual roll-out of the basically "new" game (version 2.0), a player sees the IAP element of the game reflect the need to return investment.
at this point the game is not your father's Oldsmobile anymore. It's up to the individual player to decide if the new game is fun, just like they decided when they first loaded the app. If it is, player play on. If it's not, move on.
Its easy to feel angry about this, but I'm not sure it's a fair response. I miss my father's Oldsmobile...but these games exist in the business environment we all created. If Oldsmobile just kept rolling out 1974 Cutlass Supreme's there would be no Oldsmobile's available for anyone anymore. enjoy the flower while it blooms, then when the next one blooms see what's best for you.
As a side note: Flash, if you see this, I don't comment much but I've been reading for a long, long time. I always appreciated what you brought to your posts. I always thought you were fair, which is something I esteem in people. Be well Sir.
