Savage: The Battle for Newerth (2003)
What if we told you there was an online-only multiplayer game that blended real-time strategy, base-building and technology research, first-person shooting and third-person brawling and supported up to 128 players on a single server? Definitely sounds like something that would be generating a lot of attention, particularly in a post-Playerunknown's Battlegrounds world, right? S2 Games did it in 2003 as an independent studio with no big publisher support. To say that it was way ahead of its time would be sheer understatement. It may not have been perfect, and it may have been a little glitchy, but we're only now starting to see much larger studios tackle projects that are this ambitious. S2 made the game freeware in 2006 and it was later picked up as a community-developed project that's still running today. After trying a sequel in 2008, S2 went on to make the early MOBA Heroes of Newerth in 2010.
