Mass Effect 4 will likely be one of the biggest, baddest releases of this entire console generation. That's a pretty bold statement, considering we're only a year or so into this console cycle. That said, RPGs seem to be ruling the day right now. The new technology of eighth-generation consoles has opened up so many different tools for game developers, and Bioware is taking full advantage of this fact.
A video published by Youtuber MathChief aggregates some very interesting data from around the web. He's got multiple Bioware developers going on record about Mass Effect 4. One piece of information reveals that there were only fifty developers working on Mass Effect 4 before Dragon Age: Inquisition released, but now that number has quadrupled. With so many talented people working on what is assuredly a massive budget, we only expect great things from Mass Effect's fourth iteration.
All of this projects the idea that Mass Effect 4 will be bigger than Bioware's last game, Dragon Age: Inquisition. Mass Effect 4 will be coming out next year, and by that time, the Bioware team will have had a huge amount of time and manpower funneled into the game.
