I don't care what a game looks like so long as it is fun.
One possible exception would be some of the early 3D stuff (like PSX era) in which characters were nothing but a handful of jagged polygons. That really hasn't aged well. I can play older sprite-based games just fine, but there is something about the early years of 3D games I can't stand.
The Xenosaga series is actually quite good for puzzles. Nothing really hard, but they're frequent and keep things interesting. Not as much for minigames except for that arcade game thing in the third one, which was actually pretty fun.
I had fun with Awakenings, but it really bothered me how disconnected it felt from the main game. Like your decisions there didn't actually matter. And yeah, the ending was kind of...abrupt.
The Stone Prisoner DLC was great, though I got it for free as a pre-order bonus. If I recall correctly it was kind of overpriced if you actually had to buy it. I also enjoyed Leliana's Song, but then I liked Leliana. I feel like I'm in the minority there. If you didn't like her then you wouldn't get much out of that DLC.
I can't understand why so many people are ragging on Graces. It was very well received critically and the combat in the demo was quite fun. The story might not be groundbreaking, but what Tales game is? Xillia looks better? Based on what? We know jack shit about Xillia.
Please tell me that people aren't dismissing Graces just because they don't like the character designs...
