I'm a visually impaired MOULa player (to get a rough idea, I see the world in 160x120 resolution). I like adventures, I like Myst series, although I haven't played all the Myst games yet. I couldn't be in previous incarnations of MOUL because of region restrictions of publishers, and/or poor net connection. I've been in cavern since February 18, 2010. I've made up my mind about things I'd like to see improved concerning game accessibility.
The Myst universe is heavily visual. No captions are provided for active spots, speeches are missing subtitles as well. Active spots are marked only by slight change of the cursor appearance, I noticed it accidentally after several weeks in cavern. Some areas are very dark (some of those intentionally, as a part of a puzzle), which makes finding people there quite hard for me - yes, I'm meaning Ae'gura in the first place. The chat font can be enlarged, but not enough for my needs. Chat issues are handled gracefully by BabelBot (thanks OHB).
But there are potentially very useful, yet overLOOKed features. The caps in previous sentence are intentional, I'm meaning the "look" KI command, which is location-based and has a lot greater potential than just some humorous sentences and feather stuff.
Since this is a forum dedicated to Age creation, I'd like to mention some points which could greatly improve in-game experience for disabled people.
- Provide location descriptions for LOOK command. Try to mention things which could be easily overlooked otherwise and might require very thorough search (known as "pixel hunting" in 2D adventures). You may even define device descriptions for "operating spots", i.e. places where tha avvie is moved to operate a device.
- Don't rely on single aspect of perception when designing puzzles. When it's about color, try to include sound or shape, if it's about sound, add visual feedback too (infamous organ puzzle in the first Myst, not doable without a sound).
- For dark areas, provide us with some sort of flashlight - it can cease functioning if it's necessary for a puzzle.
- Don't forget to provide subtitles for speeches, or add their text into player's journal.
- When it becomes possible, add captions to active spots (even general ones as button, symbol, lever, etc. are a great help for me). There could be alway an option to turn those off.
- If some accessibility features could spoil the game for others, group them under the separate section, so that they may be used/avoided.
I have some client-specific suggestions as well, but I'll post them into separate topic.
