I’m REALLY sorry for making a 5-month bump of this topic, but I also really want to answer the question properly.
As from the very second reply by @yotam, I don’t want the game to use the traditional “buy keys with real money in different packs, up to $99.99”. If the game allows you to buy any currency with real money (at all, no matter how expensive it is), the “amassing 100,000 keys” medal would easily be pay-to-win. (This topic was created before medals are remastered in Early Access version 16)
Instead of using the traditional mechanic that so many games used, I’d like InterAction Studios to take a risk a bit and do like Super Mario Run, Smash Hit or previous mobile CI games, which all use one-time permanent IAPs (in-app purchases). For example, one-time IAP of USD$9.99 “premium bundle” includes all of the following (the in-game notification should say that once you buy the bundle, there are no more in-app purchases).
- Chicken Hunter License (as you already know)
- 1000 bonus keys (this is only obtainable once when you buy the entire bundle)
- Remove ads (if there will be ads in the future)
- A free random spacecraft from the Muller family.
- 3 of each special weapons (is it worth the price?)
Super Mario Run and previous CI games on mobile haven’t been rated quite positive lately (Mario Run was <4 stars on Google Play, and all CI mobiles were <4.5 stars), both because users are disgusted with free trial and IAPs for full version (they might give a better rating if these games are not free-to-download in the first place). However with the new mechanic of CIU, I’m confident that this game will be better-rated.
