I think that if they're going to take inspiration from the previous TDU games, I would say look more at the original rather than the sequel. TDU1 didn't have the greatest handling model of all time, but at least they committed to an arcade style rather than trying to be both at the same time like TDU2; that, and I think it had a better, more varied car selection with some that haven't been in many, if any, other racing games. Cars like the TT Sport, Tuscan Roadster, and the various concept cars like the VW W12 Nardo and Mustang GTR were certainly unique, while the only real oddballs I can remember from TDU2 are the V6 powered Camaro, 2CV, and an old Beetle. Plus, most DLC in TDU2 seemed to overlap the original list quite a bit; having most every edition of the Zonda and Veyron, not to mention some other pointless additions like the 599 GTB China that had only a different paint scheme and maybe slightly altered interior were, quite frankly, lazy and unimaginative.
While there were some poor decisions being made, stuff like the casino was actually decent, and added a fun new way to socialize (or develop a slot machine addiction trying to get that R8 Spyder), or the wrecked cars you could find scattered across the island. That, and the fact they added a full day-night cycle with weather was a nice improvement as well. Hopefully, this doesn't turn into vapor ware, or get delayed for years on end, or end up being a buggy mess that has good ideas but poor execution like TDU2 was at launch. While The Crew is decent fun, it just doesn't feel quite the same as cruising around an exotic island at a relaxing pace like you could in TDU.
