Here's my thoughts:
- The game came out in February
- It's currently November
- Why didn't you buy the game in February? March? April? June? July? August? September? October?
- I don't think it's possible to have a coherent reason why you were able to successfully wait 10 months, and now "have to have it".
- The game hasn't had an MSRP reduction, and despite the high percentage off still costs a relatively high amount. It will certainly be cheaper in the future.
- The developer are not working on subsequent Castlevania games, if there are any, so you're not doing anyone a favour by "keeping support alive"
- No one here is giving you positive feedback about the game's qualities as a game.
