A brief history about me. I'm a relatively new costumer of Dovetail Games and don't and didn't own Train Sim Classic so far. I'm interested about the game and saw that TSC offers a variety of advantages in comparison to Train Sim World, especially in regard to route and loco variety and quantity. However, there is something which holds me of buying TSC. I bought lots of content for Train Sim World already and I'm personally not okay with paying twice for A. a second train simulator from Dovetail Games which graphicwise is inferior to TSW and B. content I already own. I would be interested to obtain TSC, but since there are no loyality discounts for me, I simply can't pull the trigger to pay for TSC and its DLCs in the same way as for TSW DLCs with better graphics, timetable services and other advantages. My suggestion would be to provide loyality discounts if you own equal TSW content. In the same way, also people that own TSC DLC should get a loyality discount for the respective TSW counterpart. So if you own for example, Dresden Riesa in TSW, one should be able to get a loyality discount for Dresden Riesa in TSC. If one owns LGV Med in TSC, one should be able to get a loyality discount for it in TSW. Not paying twice for basically the same content. In general, I'm not okay with the pricing for TSC content in comparison to other products on the market and even TSW content. Just saying this in the hope I don't get roasted for a TSW reference in the TSC Forum. But at least for me, I personally keep away from TSC and this will be my first and only post in TSC Forum, if the price policy does not change. I think a change in this could attract many players to try out the other train simulator (in my case TSC), instead of sticking only to one sim.
If you want a greater variety of content, lots of free ware, and reskins of rail stock., routes and scenarios, an easy to use editor, over 30 developers providing content, then TSC is the way to go. The big difference between the two is graphics. TSW is better but has it's drawbacks.
For TSW, you have to post suggestions "Please do a Class 50" "please do this route" "please fix this and that". TSC has a universe of routes and locos. It's pretty much all there. I disagree on TSW looking better, unless you're playing vanilla TSC with its ugly TimeOfDay files. TSW is overexposed, has broken lighting all over the place, too early darkness in summer. TSC has a way more natural look and only very soft eye adaption using AP's AdaptiveBloom shader included in the Sky&Weather EP. Also the weather changes in TSW are ridiculous (sometimes within a split second sky changes from full overcast to clear), and TSC stock with AP sound packs is much better. I can drive from London Euston to Birmingham in TSC using realistic stock from many different eras on a great looking route. For TSW, that's too long. Lower your expectations. TSW's looks are based on UE's technology, but their asset modelling often is worse than TSC's, except for the locos. (But the AP Class 37 looks much better than its TSW counterpart texturing wise.) The commercial pressure is much higher today, development must be less costly while making a route is more difficult in UE than in TSC's editor, that's why I'm glad so many things have been done in TSC that nobody can take away from me. And TSW doesn't even have a brightness or gamma option.
Seeing the other discussion - TSC vs TSW player count - I think this would be a smart move to engage players with both. DTG could put emphasis on the strength of each game. There is one big obstacle, the paid upgrades. Even though I have TSW I cannot just purchase Sherman Hill, to ease me in. SH is a simple example to why both games are great and why it's sensible to stick to one. TSC offers versatile rolling stock - the Turbine for starters but then many locos. Sure, DTM, but experience. TSW offers pretty graphics, at least judging by the contests. I assume it also runs better on modern architectures.
TSW SH is pretty poor. Borie Cutoff was omitted. Track 3 is missing. It's a much better experience in TSC. Stock has pixelated window glass textures and serious cab overexposure issues. There's animations missing on the SD40-2, just don't buy it.
