The GWE route for TSW has similar excellent graphics as CSX Heavy Haul. Only five scenarios, but many many service runs available. Many of those however are similar runs, simply at different times of the day. The tutorials are rather basic, primarly engine startup sequence, a bit about brakes and stopping at platforms.
The route itself seems quite detailed and interesting.
The engine sounds seem very muted, same with horns. I'm using headphones at max volume and can barely hear the horn whether in or out of the cab. May be different for some engines. I've only tried one other than the short tutorial runs. The B43 engine, I think.
I decry the lack of ingame help, for instance an option to bring up the startup sequences at will. I can't find any manual for the engines either. The menus for setting up runs are well done, but it's sometimes disconcerting to make a choice related to GWE and find a transition screen with CSX Heavy Haul.
Altogether my first impression is very positive, and for the intial price of $18 well worth it. I'm not a nit-picker, and don't care much about such things as amperage readings and so forth, so can't comment on the nitty-gritty stuff. I'm sure that DTG will continue improving this new route/content - their track record is VERY good as far as I'm concerned.
