Honestly I lost hope in that "thing" (to say the least)
Also for me it is too focused on the railway, given that the little done for buses is too immature, and they haven't done anything on the trolleybus sector (which I was personally more interested in).
For the moment I'm content with omsi for the modding part and the Czech simulator of SIMT, at least on the latter I'm sure of driving all three vehicles, and also spending very little compared to LOTUS!
