You can not give a straight answer without painting with a broad brush. There's counterexamples and games which fall out of the norm on all continents, and I'd even argue there is a difference in style even within "Western" games (e.g. American vs. European vs. Eastern European and so on).
I enjoy a certain style of game and in general, I do not care where it is from as long as it fits my tastes. I find most of my favorite games being 'Indie' or Japan-developed though and it is for similiar reasons as others have stated: Gameplay mechanics and certain artstyles.
So I do not care much about cineastic videogame storytelling nor most open-worlds. I'd rather have a game feature less fluff in form of hundreds of gameplay mechanics and possibilities (open world games often feel to me like jack of all trades master of none), but be allowed to experiment more with a specialized tighter set of systems. Good controls are a must, and I'd take fluid acrobatic movement over realism every day. A good RPG ruleset, a fancy fighting system in character action or a focused play on mechanics are worth a lot to me. Marry that with interesting leveldesign with secrets, some exploration and reasons to replay and I am happy. Arcadestyle scoring mechanics and balance are also a plus.
Now there are Western games which I enjoy a lot who do this, to name a few more recent (past 10 years or so) ones: Doom, Shadow Warrior, Mirrors Edge, Divinity Original Sin, Alien: Isolation, Rayman Legends, Wipeout series... and countless Western indies. For the most part, I prefer Japanese games though. There is a lot of low budget and Otaku-pandering stuff there (some of which are guilty pleasures of mine), but the mid-to moderate high budget stuff is where they truly shine, to me. Also, as someone who does not like -most- modern FPS games anymore, I really like the approach for most Japanese action games to be more close-combat heavy, so Yakuza, Bayonetta, even the action-Resident Evil games and Vanquish with their melee systems are endless sources of fun to me. Also, I still like turn-based RPG and strategy and while this is coming back in Western games as well, something like Fire Emblem, Tactics Ogre/Legend of Heroes, Shin Megami games is just my first go-to if I am in the mood. And they still put out higher budget games in surprising genres such as puzzle games, rhythm games, fighting games. Also helps that I am a huge fan of Nintendo - and there's also some examples of marriage between Japanese and Western game designs there, such as Metroid Prime or Luigis Mansion 2.
Ah it is difficult to point out exactly. It's not boobies though, even if I sometimes enjoy wellmade fanservice. For actual nudity, Western games are a lot more risque btw. and I find it strange to single out Japanese games while we have a lot of fanservice in Western games as well (The Witcher games which I really like btw. are a lot more sexist in their portrayal of women than most non-Otaku pandering bigger Japanese RPGs. And looking at games such as GTA or God of War you have two bestselling high budget games full of rampant sexism and yet discussion often points to low-budget selling 50000 copies at most niche games). For both in Western and Japanese games, you find examples of progressive depictions of women and negative portrayals. The discussion is to be had and important, but pretending it is a Japanese-focused problem is not helpful for the discourse at all. Saying "Oh you surely like Japanese games... because boobies" is the equivalent of "Oh you surely like American games... because hyperviolent gorefests".
