As someone who grew up playing savage, I'd like to get the game going again too, I miss the full servers and grow tired of small skirmishes.
Here are my ideas:
1. Pitch to streamers, not a bad idea, if we hit the right streamer we might get the numbers going again.
2. Reddit/other social media. Reddit has loads of subreddits and even has one for older games.
If we got a few guys to bump the up arrow on a reddit post about savage in one of those forums it could draw some small attention.
3. Put videos on youtube: Some of those older videos have close to one hundred thousand views.
Those are my main ideas, open to suggestion. This games a part of my child hood, but more importantly, if i ever want to get good at this game, i need some targets, so lets make it happen guys.
