All Tomb Raider games are on sale on Steam. If you like action/exploration games and you know what else, some of the best ones are on sale for less than a dollar!
I can’t speak for the classic games, but of the newer ones Tomb Raider (2013) and Rise of the Tomb Raider (2016) were really good.
The latest one, Shadow of the Tomb Raider (2018), ehhh I found a bit of a slog. It just felt very low effort compared to the others and the world/story were uninspired.
