Slay the Spire (£19.49)
Word of mouth has propelled Slay the Spire from an under-the-radar early access game to a full-blown indie smash, including critical acclaim and an "Overwhelmingly Positive" Steam user reviews.
What's the big deal? See, Slay the Spire finds the middle ground between a challenging, dungeon crawler-esque roguelike game and a single-player deckbuilder experience, tasking you with battling through waves of monsters with your various cards. It's a clever blend that's hooking players en masse. Believe the hype!
Half-Life 2 (£7)
Yes, it was originally released in 2004 - but that doesn't stop Half-Life 2 being an all-time great adventurer, and that remains very much the case on this Mac port.
Playing as scientist-turned-saviour-of-humanity Gordon Freeman, it's all on you to fend off the aliens infesting the planet. Deploy your wits and weapons - including the immense gravity gun - to free humanity, while enjoying the award-winning physics, graphics and human emotions which made Half-Life 2 such a success.
At £6.99, it's a steal - and the perfect thing to keep you occupied until Half-Life 3 is confirmed. Which will probably be sometime in the 22nd century.
League of Legends (Free)
League of Legends is the Mac and PC multiplayer phenomenon that just won't fade away even after a decade of popularity. The 5v5 multiplayer online battle arena (MOBA) game challenges you to team up in tactical skirmishes to take down the enemy's turrets and eventually topple their base.
With more than 140 playable champions in the game, there's a huge amount of gameplay variety included, and plenty of strategy to consider as you get into advanced team compositions. Did we mention that there's a massively popular esports scene? Even if you just want to play around for kicks, League of Legends is great fun. And it's free-to-play, albeit with a limited set of champions available from the outset.
Counter-Strike: Global Offensive (£12)
Decent multiplayer shooters are few and far between on the Mac. Sure, there are some Call of Duty ports kicking around, but for engrossing, button-mashing combat there aren't many places to turn. Thankfully, Counter-Strike: Global Offensive is all the gun-toting you'll ever need.
A steep learning curve only adds to the addictiveness, as you utilise a range of unlockable weapons to fight insurgents as a counter-terrorist - or vice versa - battling across 7 maps where death is always right around the corner.
Yes, CS:GO is pretty infamous for its vast community of online players, many of which are less-than-welcoming - but that doesn't take away from the fun of honing your skills and shooting into the early hours.
StarCraft II (Free)
StarCraft II is several years old at this point, but it remains a real-time strategy classic. And yet there's fresh reason to play it right now, especially if you haven't before: Blizzard recently made the original Wings of Liberty campaign and the core online multiplayer experience free.
Yes, free! This sci-fi sequel is worth your cash, but now you won't have to spend it – that is, unless you want to buy the expansions, which are sold as add-ons. Not only can anyone enjoy it now, but the shift to free-to-play surely means more active online competition to trounce.
