Demos are great. Th🏅ey give you a chance to try out a game before you part with yo꧙ur money, are usually free and almost always give you the same thrill you get from playing a full game when you start it up.

But sometimes the publisher in question goes a little too far with their generosity and gives us a demo so great it could almost be sold as a standalone game꧃.

now anyway, we might as well go ahead. So here they are: The Top 7 demos of all time.

7: Panzer Dragoon Saga: Disc 1

This demo is so great because it is the actual game. Well, a quarter of it. The UK's Official Sega Saturn Magazine scooped this amazing coup to bring disc 1 of the four-disc Panzer Dragoon Saga to readers, sellotaped to the front of the magazine. Imagine if disc 1 of Final Fantasy XIII's first disc was given away on a 360 mag - it would be that big a deal.And, funnily enough, it was a big dea𒈔l.

Check out this video of one of the demo's mosty memo🤪rable encounters. Feel the quality - the fully voiced characters, the sense of scale, the innovative real-time turn-based battle system with its circular positioning system.

One idiot sub꧑sequently wrote in asking when they'd be running the next disc from the game on the cover. It doesn't work like that, son𝓡ny…

6: Lost Planet

OK, so the finished game wasn't all that brilliant. But as a demo for the brand new Xbox 360, it was sensational. For starters, the taster gave you two big areas to play around in, 🐎so you could sample the snowy wasteland (plus indoor sections) and an underground lair.

Then, it gave you several weapons to play ꦑwith, including the walking mechs. Add in enemy-spawning pods that you could explode at will and you had yourself a party.

It also threw some astonishing, Matrix-esque visuals at you. Being inside the hive and seeing all the Akrid flying around above you was frikkin' epic when you were used to PS2's modes🅺t capabilities.

It kept on giving, which is why it's here - two huge boss battles were the icing on the cake. Qu✤ite literally, in f🦄act, as their ravaged bodies turned into huge ice sculptures waiting to be smashed with a single bullet.

T🐓his demo was next-gen gaming summed up🦄 in one delicious, free morsel.
