DOA2U was my first Dead or Alive game. It was actually my dad who brought me into the series, he was playing with a couple of friends and asked me if I wanted to try. 'Okay' I said, and looking through the character screen, the first character I ever played was Jann Lee in his C2. I liked the originality of the fighting system and the stages looked amazing. I've played that game
a lot, and ended up being somewhere in the top 20 in the online leaderboards before the online feature of the game was shut down.
At a later point in time I moved on with DOA3. That game was amazing, I have no words for it. Then DOA4. Even though I got progressively better with time, I didn't become one of the top players like ZakkuRye, Offbeat Ninja, members of 'Electrified' and so on. I was never able to surpass S rank in DOA4 myself, and didn't really bother to play the game on a competitive level.
About six (!) years later: DOA5. Played the Alpha demo extensively with my dad, in which you could you Power Blows an endless amount of times xD. Got the full game three days before official release, and again the first character I picked was Jann Lee on the stage Sanctuary. Doing some free training, I realized how much different the game was from all the other DOA's I've played. It was a bit overwhelming for me with all the new features: Power Blows (with which I was familiar already), Critical Bursts, new moves, new stages, new characters, completely different graphics, new character voices for some characters, etc. I sticked with Jann Lee, and then decided to learn Mila, Rig and Kokoro. Dropped Mila in a couple of months. Also looking at the characters I noticed VF characters were there, but I was disappointed with the exclusion of Jacky. All my friends were like: 'Who's Jacky? O_O'
In 2013: DOA5U. Was pretty hyped at first since I heard my favorite NG girl Momiji and favorite VF character Jacky were in. In the end I didn't buy the game day one since I thought it was unfair and cheap from TN to release the same game twice with just some additional features. After two weeks I decided to buy the game and this is actually where it all started for me: I devoted myself to becoming a competitive DOA player. I learnt frame data and as time went by I got the hang of the advanced fundamentals, such as: Punishing (whiff punishing, throw punishing and strike punishing), slow escaping, learning max damage combos, fuzzy guarding, etc.
In 2014 I met Gehaktbal on DOA online and a couple of months later I met Pictured Mind. Still willing to become a better player, we organized an offline session, had very good games and above all: I learned a lot.
Fun fact: This was about the point in time when I created my FSD account. Despite having played DOA for so long, I'm only part of FSD for relatively little time. Afterwards I went to an offline tournament, and in 2015 I went to another live tournament.
DOA5LR: All I can say is I'm still learning and improving and I'm enjoying the game even more now that I understand the fundamental mechanics of the game.
