Train Simulator: Köln Airport Link Route Extension Add-On

I'm going to have to throw in with the negative reviews on this one. I'm a bit torn though. I did enjoy playing it, but... + It's a really nice addition to the Koln Koblenz route. It's not long, but a nice amount of things to do. + The scenarios are mostly nice. They can all be completed normally - none are broken in that sense, but... - One scenario gives you 0 xp. This breaks one achievement for sure. - Also the achievement that tracks points up to 8600 stopped counting/working for me after I ran the aforementioned scenario. That doesn't make sense to me, but it's the #3 scenario and I collected 2000/8600 points and nothing counted after that. - Unlike most German routes, there was a distinct lack of signage when it came to speed changes. Not only did the HUD not work which is normal, but there was missing indications so even if you don't rely on the HUD you still had to guess at speed changes. Annoying... Food for thought: Why is Dovetail so lazy at testing? If you don't care about achievements and getting gold stars on your scenarios its probably just fine. But that's what I care about, so two thumbs down.
