mqstout: Question: How do you feel about games that "genre mash"? What's a good mash you've played, and/or one you hypothetically think could be awesome?
(Genre mash examples: Aforementioned Lords 2, turn-based empire management with real-time battles. Or Dynasty Warriors Empires, button-mash battle resolution to a tactical battle map.)
I would say it as follows:
If all the genres mashed together are essential parts of the game, and are prevalent throughout the whole game, then this could work well.
One that I have played is Magic of Scheherazade. The game plays like an overhead view action game (like Zelda 1) much of the time, although the game has towns and experience levels. However, every now and then, when going from one screen to the next, you get into a turn-based encounter, which plays much like the JRPGs of its era. (With that said, there were some interesting mechanics there, like troopers, having all rod/arrow attacks working at the same time, and even combination spells (way ahead of its time here).) This is rather interesting, though if you choose the wrong formation, a battle could take a very long time, and some enemies have instant death attacks. (If the main character dies, you lose one of your 3 lives and the battle ends; if someone else dies, the character is unusable until you go to a mosque, and sometimes a certain character needs to be alive for you to progress.)
I could also mention Undertale, which I still haven't played, but whose battle system combines RPG menuing and bullet hell dodging.
On the other hand, if a game is mostly one genre, but requires you to play a minigame of a different genre to progress, that is bad game design. Somebody might prefer to play RPGs due to a condition that makes them have horrible reflexes; forcing them to play an action game to progress is likely to make the rest of the game inaccessible to that player. Also, when I play an RPG (for example), I am in the mood to play an RPG, not an action game.
Have you ever been unable to finish a game you started because of a part where the game forces a minigame on you that you haven't been able to complete? Alternatively, is there some game that you sometimes think of replaying, but never (or rarely) actually do because of some out-of-genre part that you dread? (Chrono Trigger with its button mash event and Zelda: Ocarina of Time with its insta-fail stealth sections are two examples for me.)
