There's a fan game I've been following on and off for the last year and half and it's made some significant progress almost being complete.
This is it. This is probably the best successor to (classic) WipEout we'll ever get. It's the most authentic 1:1 clone of WipEout 3 you can get. The UI, the art style, the graphical style, the track design (for the most part, not perfect), the stellar EDM soundtrack, sound effects, and iconic WipEout physics. Even has that nostalgic PS1 texture jitter.
It's still a bit rough, but again, it's not done. Some menu tweaks and track refinements would be nice, but that's about it that I can criticize of what we have. If you like WipEout or just futuristic racers with an emphasis on crisp racing lines this is free on Steam right now and what it's got is pretty rad. Gonna hold me over until Formula Fusion is playable.
