Train simulators are pretty cool. I've played MSTS, Trainz, and DTG's Train Sim Classic and Train Sim World. Trainz has route creation, which is fantastic. It's like building a model rr without the expense and with nearly unlimited space, structures, track, and trains.
I agree that Lionel should get into the market of V-Scale more. I do have Lionel Traintown, a PC game from the early 2000s. It's basically a puzzle game with Lionel Trains. The game has great graphics for such an old game, and I still love playing the game occasionally. The interface is very simple; all you need is a mouse and keyboard. Players can run trains, design and build layouts, transport cargo and passengers, solve puzzles, repair the track, and even learn about how real railroads work. Plus, there are alien spaceships, a sea monster that destroys bridges, dinosaurs, rubber ducks, and fun animations at each industry. Of course, there are quite a few funny things when you highlight certain buildings. The maps include a desert, a forest, a backyard, a living room, and even an alien planet.
I think Lionel (and other toy train manufacturers as well) could work with game developer(s) do one of two things:
1.) Remake the Lionel Traintown puzzle game with new animation, new puzzles, new trains, and of course, references to the old game.
2.) Make a model rr simulator with many different scales, models of locos from numerous companies (US, European, Asian, etc.), and of course, operations with animated accessories.
My model rr simulator idea could also include simulations of track laying (including flex and sectional track from multiple manufacturers), wiring (soldering included, too), transformers, command control systems (DCC, DCS, Legacy/TMCC/Base-3), scenery, structures, and of course, running trains. DLCs could be added later on for more fun.
As for benchwork, I'd prefer if the game did preset benchwork for a new layout. Just put in the dimensions and boom! Instant benchwork! Then a player would chose a scale they want to model and get started.
Scenery would include backdrops of different cities from all over the world, deserts, forests, rural areas, industrial and yard areas, mountains, etc. More backdrops could be added later on with DLCs. Maybe backdrops could be added from actual photos.
Of course, there would need to be tutorials included that help new players get started in the game. These would begin with setting up a 4'X8' table top, building a simple loop with a siding, wiring, and running a train. Then comes scenery, structures, and finally, expanding an exisiting layout with other tables. Block control and command control would need to have their own tutorials. Finally, a basic operations tutorial series could help players who like to operate their trains like the real thing get started.
Best of all, players could enjoy all the aspects of the model rr hobby without paying a single dollar (except for buying the game, and maybe DLCs, of course).
So basically, this Model RR Simulator would be like Trainz, but with actual model trains.
