In my eyes, DOA5's biggest competition is every DOA that came before it.
Comparing it to Tekken or VF or SC or 2D fighters doesn't matter when it has trouble living up to its legacy. Rushed or not, a lot of the content, modes and otherwise, are remixed in ways that make them less appealing than they were in previous DOAs. The costume selection is better than DOA3 and DOA4 but still not back to where it was in DOA2U (second, third, seven-hundredth release or not--it set a standard). Half the stages are also very drab and boring in comparison to those in earlier games and even some within DOA5 itself (in terms of color palette and art direction, size, shape, locale). Music is largely forgettable, and it hurts to hear some of the older songs only appearing in story mode. A lot of the tech porn like pretty reflections and deforming sand/snow are gone, too, in favor of prettier character models.
It's just really hard to complain when the fighting is like it is now, though, because, ultimately, that's the most important part. DLC could fix complaints with the content (stages and costumes) and polish (netcode, UI). I would love an option to add in better music or the option for character themes to show up from the earlier games, at least.
DOA5 is a good foundation for the future; it just feels a little lacking. I still think DOA2U should be held as the standard for single-player DOA content, not just regarding what modes the game had but how it executed them, too. A lot of the new course crap post-DOA
doesn't do it for me. Replaying the same ones over and over gets boring because barely anything changes. If things must be standardized that way, there could at least be more attention paid to providing a pleasing variety in order to boost longevity. There's such a glaring lack of polish when it comes to a few things--even the UI doesn't tell you what you need to know when you're going for individual character records like it did before and stuff like that. Some menu options are toggle, some aren't. Some settings don't get saved, some do.
You can tell which fighting games are timeless and which are stopgaps until the next iteration. Most of that comes down to detail and polish in all of the "little things".
That said, I'm happy with the game and hope we get some patches and DLC.
