I don't know that the handling is particularly advanced, but I remember it holding up really well to CTR. Maybe it's just that I haven't played CTR in a while. I think one thing both games have in common is challenging AI and some interesting shortcuts in the tracks rather than just basic circuit designs.
WDWQMRT isn't, like, on the level of Mario Kart DS with snaking, but it's probably the game that comes closest in my estimation from those I've played, at least the ones this side of the Sega All-Stars series.
Ah that makes sense. Yeah I mean I did enjoy it at the time.
The reason I like CTR though is in large part, because the boosting mechanics are so indepth. There are five different types of boost (level 1, 2, 3, sacred fire, and ultimate sacred fire) as well as something called the 'reserve' system, wherein left-over boost stacks into a reserve 'pool' which can be consumed to take elaborate shortcuts.
It all surmounts in a system where in CTR, you're playing 10 turns ahead to have enough reserves to take the shortcut you need at the end of the lap. It has near endless mechanical depth and lends itself to very strategic play. And this at a time where the current gen counterparts like MK8 are actually quite shallow.
On topic, at least Sonic Racing has some interesting team mechanics that should add depth to the game. I imagine the slingshot boosting system can be leveraged very effectively by especially coordinated teams. Team racing has always been fun for me. The team mode in Dirt Rally 2 (different type of game, I know) was my favourite.
I think in general, the lack of team racing is part of what makes racing games less popular than other genres. People like to work together towards shared goals. I really hope the team racing thing is an option online, as I'd like to play with friends and maybe team up with some of you folks from ERA.
