Thanks to hardware like the Shield TV and Android-compatible game controllers, it’s easier than ever to play PC and console games on your Android device. Since Google Play allowed games that require controllers, the official Android app store has become home to hundreds of titles originally released on Windows, PlayStation, Nintendo DS, and other platforms.

While iOS devices could theoretically run some of the games on this list, only Android users can play them on their smartphones, tablets, or Android TVs. That said, you’ll need a higher-end device to play games with HD graphics, and most console titles require a controller to play. If you have the right hardware, the following games are worth downloading on Android.

This game is an absolute gaming classic. It’s short, but it won’t linger too long as you quickly discover the secrets of Aperture Science and its Portal Testing Initiative. GLaDOS, the omniscient and evil super-AI, remains one of the greatest villains in gaming. The puzzles and atmosphere are still brilliantly done. This game is a must-play for everyone, and if you haven’t tried it yet, why not grab an Android device and give it a go now? And if you want even more Valve classics, Half-Life 2 (based on Half-Life 2 for PC) and the first and second episodes are also on Android, although Portal 2 has not yet been released on Android.

The trial platformer genre has become popular on mobile, and many of the games owe a huge debt to Team Meat’s take on the genre. Nvidia helped port it to Android, and you can see many of the elements that have made other games in the genre so popular. You’ll need a controller; the game would be far too difficult without one. The challenges are brutal but plentiful and rewarding, so if you can pull this one off, you’ll have truly proven your skills as a gamer.
