I find it interesting as to what some people call "gamey."
It is a purely subjective term with no formal, or agreed upon criteria. Essentially it is a meaningless term.
On the other hand, the Devs have created several tools. I suspect that some are based on historical situations, to make game playing easier, or, for reasons that are unknown to us players. These tools include things like, "magic move", pilot training from day one, ZOC, hexside control, instant pilot replacements, the magic highway, R&D, aircraft/engine production, resizing of air groups, etc. Obviously many of these are Japanese options only.
All of these tools could be, many have been, called gamey by someone.
There are also exploits that may be caused by coding errors, unintended consequences of coding, or something overlooked. Most of these have been pointed out and corrected, others may be being used unbeknownst by the player.
