Fulfil your inner engineer with Besiege: construct medieval siege contraptions to lay waste to countless conurbations, with a building system simple enough for slaughterers-in-training, whilst sufficiently complex to fulfil the cravings of infinitely creative conquerers.
As it's still in development (or 'early access'), by playing Besiege on your Mac you get to help the developers improve the game whilst you fill your hours flattening fortresses.
Concentrate your cranium with hatchet-job science to create clever catapults, monster manglers and terrific trebuchets, with all the resulting destruction rendered in glorious 3D (complete with Michael Bay-like explosions).
XCOM 2 (£48.99)
Aliens rule the earth. Society seems shiny and great, but dissenters are bumped off like it's 1984. Welcome to the world of XCOM 2: a strategy title where the remaining members of a tiny resistance force must battle to rally troops and face-off against their alien overlords.
Blending classical strategic planning, tactics and development with gripping combat interactions - all in visually rich detail - XCOM is one strategy game that won't leave you bored. Throw in new enemies and an immersive story and XCOM 2 is destined to steal hours, if not days, of your life.
Better yet, there's a whole community behind XCOM 2 developing mods that make it even better.
Farming Simulator 17 (£33.99)
The title says it all, really - but don't go thinking this is just some crop-cutting bore-fest. See, the FS series has captured the imagination of the internet, which means there's a whole host of mods out there - as well as a barrage of YouTube videos - which make it a real sack of laughs.
Head into FS 17's online multiplayer mode and you can expect carnage, as combine harvesters, tractors and the rest wreak havoc in fields of sunflowers, soy beans and more.
This edition delivers new vehicles, environments, animals and more - so there are even more ways to get flat cap happy.
Half-Life 2 (£6.99)
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.
Motorsport Manager (£24.99)
Reckon you're the next Briatore? Think you could trump EJ? Put your mettle to the test with Motorsport Manager - probably the best racing management simulator that's ever been made.
Originally a beautifully realised smartphone game, it's now hit the Mac - among other platforms - with greater depth, richer graphics and generally more addictive gameplay.
From founding a team to hiring and firing drivers, tweaking car setups to making in-race calls that could make or break your championship, Motorsport Manager is a must for race fans and sports know-it-alls alike. And it's perfect practice for the real thing.
Counter-Strike: Global Offensive (£11.99)
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.
Originally launched in 2013, Rust has been rebooted for Mac - and, while that hasn't gone entirely to plan, with plenty of development issues, it's still a cruel, immersive survival game that will test your patience.
It's multiplayer-only and, really, you need to play in a group. Play alone and all of your hard work - building shelter, finding food, crafting some semblance of a life for yourself - will almost definitely be raided and decimated by a bigger group of players.
Still, if you can get into one of those groups - and don't mind frequent savage turns - then you'll love Rust.
