When I thought about this, there are hardly any generally "good genres" in my world. A really good game is good in any genre. But I did miss a few in the list:

- Card/board games implemented on computer. (Chess, Bridge, Mah-Jong etc.)
- Small diversion games like the classic 2D games.
- Programmer's games. (PRobots, ChipWitz, Core Wars...)
- Turn-based strategy games. (I prefer them a lot over real-time ones which tend to be all about clicking the right commands fast enough).
