DX:HR is getting boring fast due to lack of variety, lack of quests, and too much emphasis on stealth. I love stealth, but when I play an rpg I want to do things in a multitude of ways. Skyrim kind of renders DX:HR obsolete months after its release due to its very existence.
On the other hand, there's Witcher 2, which manages to weave tight narrative with great combat and OPTIONS. Now that's a real rpg, which I can't say for DX:HR.
Still going through Final Fantasy V, I'm on world 3 so I'm near the end and should beat it this weekend. Playing FFV alongside western rpgs really exposes my modern tastes. I still like jrpgs, but even though in many ways they're mechanically superior - and even then, games like Witcher 2 show that wrpgs are stepping up to the plate - they're just so fucking simple. I know I'm saying this in regards to FFV, a game released in 1992, which I adore, but it's just how I feel. It is taking me forever to go through a game that takes me all of sub 20 hours to complete.
Borderlands also owns.
