Even though I agree with you, I still enjoy this style. Just like a lot of current games
are first person shooters, I don't think that it's a problem if numerous games share a
specific style or gameplay. Of course, like you've said, there are a lot of games that
use this visual approach so just having a pixel-art-style doesn't necessarily make a
game unique anymore. You need something like unique game mechanics / ideas or a
really good gameplay to make your game stick out.

Well, I guess it's not a bad choice to try it out at least...
Anyway, thanks for the reply.
