Sale calendar
The year in sales, so you know whether to buy today or hold a few weeks.
Neither store publishes its calendar far ahead, but the big events fall in the same weeks every year. The dates below are the usual pattern, not promises; the stores confirm each sale a few days before it starts.
How deep the cuts go for this genre
Tower-defence games are cheap to begin with and discount steadily rather than dramatically. Older titles on our list such as Defense Grid 2, Sanctum 2 and Bad North routinely drop to a few pounds in the big sales; recent releases such as Cataclismo and Diplomacy is Not an Option have sat at 25 to 60 percent off in their first year or two, and GOG's Halloween sale had both at a third of the usual price when we checked. Thronefall and Dome Keeper rarely go far below their list price, and do not need to.
Timing a purchase
- Want it now and it is under £12: just buy it. Waiting four months to save three pounds is a poor trade for a game you will play for fifty hours.
- Want a £25 game in October: the autumn and winter sales are weeks away, and both stores will cut it.
- Watch the usual price we print next to every sale price. A struck-through figure tells you what the discount is really worth.
