Hmm I don't know if I should put all the enviroments into one review on Valley but I'll do it anyway.
If you played the original Trackmania then this shouldn't be a surprise because everything is particulary the same, which is a good thing! I've loved the original Trackmania since I've seen about it back in my middle school years. Played the demo of Trackmania Sunrise and enjoyed the series ever since. I met some really good people and friends and actually played competitively in this game, but it didn't last long.....sadly
Now here we are with the next Trackmania game, with improved visuals (which looked amazing) and a lot more options with editor (objects, scripting, etc.). Since I was a really into trackmaking, (and I still am!) I really enjoyed experimenting the new block that they offered. The replay editor is more of the same with some new features that I can't say but I know for sure that all of the old editing equipments are still there. I like the fact that now I can take a screenshot of the car moving without having to shoot a video and screen capture it from my computer. What I also like about what Nadeo did is that they added a simple editor to the replay editor for beginners and not just the editor mode. All the enviroments are very unique from the looks to the driving style. Canyon is more of a drifting enviroment whereas Valley is more of grip to slidy dirt sections. I like the fact that they didn't change any of the aspects that made Trackmania great and added new features. Manialink is back and from my experince it hasn't changed, but I never really looked at it often. I recently looked at the paint editor and Nadeo seemed to changed some the UI. I can't really tell since I didn't really put the time to mess around with it. I also really like the fact that Steam is intergrated with Maniaplanet, but the the negative side to is that most of my friends don't have Trackmania, so it's kind of pointless to me. Ok now lets talk about the three enviroments.
Canyon was my first experince that I had with the the new engine that I played a year ago. I really enjoyed the handling and the drifting aspects of it. It's a great representation of the Arizona desert with large canyons and little plant life. I like the fact that it's easy to drive but hard to master because seeing how the competitors drive this car is utterly insane. I do have to say it's the least that I played so far, even though I put a lot of hours in it. The one thing that I do get annoyed is that the vehicle snaps when I'm counter-drifting. This only happens when the car was about to straighten itself out.
Stadium for me is the new remastered version of the previous Stadium. I do have to say that surprisingly they changed the physis in this enviroment. The vehicle seems a bit slower than the origanal enviroment and the handling is less stiff the the previous. I still enjoyed the enviroment regardless becuase this was the enviroment that I played the most from the last Trackmania (Nations ESWC and Forever being free). I really like the improved lighting effects in this game, it gives more of a beautiful look to the enviroment. There were also some new blocks added to this version!
What I did feel dissapointed is that the bugs are still existant from the last game, but it doesn't interact often. Like for instance when landing on the dirt portion on all four tires causes the vehicle to slow down. Another bug is that when the tires touches the side road on the asphalt, the vehicle will randomly lift itself in the air. It might seem small but from a competitive standpoint it's annoying.
This being a remastered version of the origanal Stadium, I'm glad that they sold this for 10 bucks.
Valley I have to say is an intersting track, to say for the least. And what I mean by it being interesting that dirt section. Not only it's hard to control since the car can easily oversteer if turned to much. For people that doesn't have a medium/high spec PC, it can give performance problems thus making it less enjoyable. I do have to say that this envioment is the most exqusite out of the two. It's a beautiful reference to the Euproean Nations and even thought it doesn't really have the "valley" in it, it's still somthing to look at everyonce in a while. After playing it for so many hours and trying to get the hang of the handling model, it becomes really enjoyable, making it my favorite enviroment.
If you're a new player interested in this game or a old veteran trying out the next Trackmania game, please give it a go, try the demo. You wont be disapointed.
TL;DR, It's a really good game that I would recommend playing!
