I'd plan on doing the following maybe;
- Mostly major/landmark/famous titles (can't write them all of course).
- Two parallel lines: one with only the original year of release, one for the ports release dates ? Or just one for the arcades and the other for everything else ?
- 'Eras' more or less distinguished by a specific year or game, or console generation (or all three at once?)
Here's a very early, rough draft list below with some titles, more or less sorted by year and vague eras. No attempt at a double-timeline arrangement yet.
I have no precice-enough idea, so don't scream at the lack of Amiga or whatever, questionable picks, errors etc, I will take my time to perfect it.
All suggestions/critics welcome! Thanks
