Absolutely not, it's either DOA5 or DOA2U.

My favorite is DOA5 LR.

You can test it for free. Why not trying and then decide yourself if its ok.
I own Doa5 LR, DOA 5U and DOA6 and they have all their positives and negatives.

But actually the most important thing is the modding community + cheatengine tables. Without those DOA won't be DOA, at least for me (SP and local VS only).
And also here you get good stuff for both DOA games on PC.

DOA5. I liked everyting in it: stages, guests, tag, skins...

Definitely 5LR. It had my two mains: Leon and Gen Fu and didn't have that stupid, automatic noob-combo button.

DOA5LR for me too. It's the most complete game in the series. Too bad the PC version comes with no lobby and missing stages

6 is best

6 it's a much better product IMO. I've played a lot Doa5 (bought the collectors edition in PS3, the ultimate edition and last round in PC and PS4) and even it's very fun still it's a somewhat dark game with a sad pallette. Reshade can improve this but there's no way to compare to the vibrant and shiny DOA6. Even the mechanics are better.

DOA4

DOA4 is the best for me. It's my most played DOA game, and I still play it once in a while. It's a product from a different time, the golden age of gaming, and I don't think it will ever be recreated by a new DOA game. No paywall DLCs, just unlockables, character endings, costumes, guest characters like Tengu boss from DOA2 and female Spartan from Halo, all unlockable you get just by playing the game. And the online mode with customizable avatars and open world lobbies was way ahead of it's time, way before Dragon Ball FighterZ, Street Fighter 6, and Tekken 8 did it.

I must have spent hundreds to thousands of hours in DOA4 between grinding to unlock unlockables and in the online mode, walking around lobbies, hanging out with people watching fights on the big screen, and grinding fights for those Zack dollars to buy customizations for my avatar. I played DOA4 for years, pretty much the entire Xbox 360 generation. I got DOA5&6 on their first day because DOA4, but I only ended up playing them for several months before I got bored. Paying for more DLC costumes just doesn't keep me excited to keep playing as much as unlockables and avatar online mode.

^I really hated 4's lack of balance, especially with Alpha 152 and Christie, and it had by far the worst version of Leon in the series. But the female Spartan was awesome (and bogarted half of Leon's best attacks, but I digress) and OG tengu was fun to have. The online mode does sound a lot better than 5's, though.

As for the golden age of gaming... yeah, it was. There were no mircotransactions, no Denuvo, no always-online BS, just games that had to succeed or fail as games. And they had patches, so it really was the best of both worlds. These days every AAA studio that makes a great game has it infested with DRM malware and gets shut down two months after release whether it succeeds or fails. I miss the good old days when buying a big-budget game wasn't a deal with the devil.

I miss those golden days of gaming, I remember back when I had the original Xbox, DLCs were just becoming a thing, and they were free. It was a great time, before someone came up with the idea to charge money for DLCs. Free new stages for Splinter Cell, free Hurricane Pack update for Ninja Gaiden, adding more content like new enemies, weapons, mechanics. Only Internet wasn't big back then so they made Ninja Gaiden Black with most the Hurricane pack content for people who didn't have Internet, well minus the intercept parry move because it was too OP. And before DLCs they were still finding ways to add new content. I remember grinding DOA2U to unlock the booster pack that added new costumes to DOA3.

werybest!!!!!

I like DOA6 over DOA5LR for both mechanics and graphics.
