DTG JD TrainSim-Matt you asked about accessibility - I've had a bit of exerience in accessibility for daily life and for software first up take a look at WCAG https://www.w3.org/WAI/standards-guidelines/wcag/ - while this is aimed at websites a lot of it would be transferrable to the games - things like levels of contrast, font sizes, ability to work with screen readers etc. I wear glasses for reading and have a deaf brother so am a big advocate for accessibility - here are a few things I would like to see to help everyone High contrast for text - text needs to always have a background not render on top of whatever is on screen with no background - most places in the game are fairly good but there are places with transparent background and even no background which is hard for low sighted people. Different people have widely different contrast needs so it needs to be configurable for foreground and background colours Access for screen readers (or have it built in - eg hover cursor over something and button) to read aloud all important text in their localised language - these are important for low sighted people who might have enough site to be able to play but not read dyslexic people people who simply cannot read but can understand spoken words On screen sub-titles whenever there is speaking or there are noises important to immersion When a person speaks (e.g. tutorial) When a train speaks (e.g. German locomotives) When a train makes noise or there are background noises e.g. <<engine sound increasing>> <<car horns toot and traffic noises in background>> <<people talking in station>> <<brake application sound>> <<flange screech>> Size of active areas for switches and levers for people with less fine motor skills - not everyone has fine control over their hands and may be using game pad controls built into a wheel chair - its important for everything that can be activated to have a large area for selection of that object. That'll do for now. I'll go dig out some of my guideline documentation and enrich this as time goes on but others might like to add their thoughts here too.
