The much-reviled UI conspires to halt your progress, but behind all that, the game is as satisfying and addictive as ever. Once you figure out what you're supposed to do, there's a good spread of skill games and other challenges that mix things up with the standard Trials medal and leaderboard-chasing.
Seriously, though, the front end. I could (and might) write a whole article about how how it obfuscates and traps the player, and how inappropriate a map interface. Not a single Trials player cares or even knows where tracks are geographically set, meaning the icons are essentially scattered randomly around a large scrollable region. Even if you use the filters to narrow down the icons, there is still no order to the results. It's liking asking an archivist to retrieve some some files, and they climb up to the mezzanine and empty the box of documents all over the floor, leaving you sift through the mess.
You need to gain XP to unlock new tracks, but finding where to get XP is a not-very-fun treasure hunt. After a while you'll work out that 'contracts' give the bulk of the XP you need. Some actions randomly unlock new 'sponsors', and suddenly a whole load of new contracts are splurged all over the map. I only worked that out after 20 hours. When I first started playing it on release, I tried for ages to complete a backflip contract on an Easy track. Much later I realised that although the track is Easy, the contract was 'Extreme'. Why was I given an 'Extreme' challenge so early on? I stopped playing it for a year due to all the confusion.
Then there's the loot box cosmetics. It's one of those games where loot boxes contain fairly boring things, so as an adult gamer I can't really be bothered to open them. I have over 100 of the things, and there's the customary 10-second fanfare every time I open one, designed to promote the release of endorphins or something. I will never be bored enough to spend 20 minutes opening those crates, meaning even if I wanted to customise the look of my bike and rider, there's a tedious barrier in the way.
But it's Trials, possibly the best platform game ever. There are a shit-tonne of tracks, all of a high quality. The difficulty curve is well-judged this time. The best bit is Trials University, which I mentioned earlier in this thread. This teaches you advanced techniques like slope landing and rear-wheel hopping, and genuinely helps you improve your skills, making Hard and Extreme obstacles seem do-able.
I got as far as completing the Grand Finale, and cleared all the Extreme tracks, except for Inferno V (Inferno is always the hardest track in Trials), on which I can't even make the first jump.
If you can get past the terrible front-end, it's classic Trials.
