I'm really cruising through my game now. Making a lot of progress. But I'm thinking about other potential games as well, including Superstep's idea. Some of the concepts I've entertained is a day and night cycle, clothing (instead of equipment), and maybe having your character have to eat and sleep. Don't know about that. If there was a day/night cycle, I'd like it to be slow, and count down in a real time for about an hour per day, and an hour per night. Maybe traveling by public transportation would take time out of that.
I'd like it to be serious, but also humorous. Well, mostly humorous, but with real-down to earth characters. I know I've mentioned a murder mystery before, but I can't shake the idea that in the end, it turns out no one has been murdered, the character just fell down a dungeon or got put under a spell or something. I don't know.
I like open worlds, and even Forgetter is kind of an open world game, so would Superstep's game. Just maybe you would open parts of it at a time.
I also think there should be an inventory for objects, keys, books, and other items you collect to take and give to people you talk to, etc.
Anyway, gonna finally get back into Mass Effect tonight. I miss it. Just been working 16 hours a day on the game, as well as finishing up a poetry book.
