Just tried out the new system, not being sure about what I would think about it. Is it a good replacement for the old baseplates? In general, I think it is very nice that the system enables and invites to be more creative about the layout. Also, the accessories such as the lamp posts with glow-in-the-dark pieces are a nice touch. The roads are shiny, whereas the old road baseplates were matte. This is a matter of preference. I wonder how the roads would look after a lot of play. Looking weathered they might even look better. Time will tell. The pros: - As far as constructing the roads, it is easy to quickly build a layout - The roads are easy to make wider, for e.g. Speed Champions cars, or to make highways. Overall versatility is good - looks good (in my opinion)
The cons (or areas of improvement): - There are too little tiles included to build even a basic four long (plus zebra) section, so you'd have to get that from pick a brick or BrickLink or the like. - Picking up built sections is difficult, because they will easily come apart - It is not possible to build the standard/intended road width with the gray tiles aligned on the sides, while simulateously connecting the road sections to the surroundings. There should have been a way to snap plates onto the underside (without raising the sections) that may then stick out of the road sections. - It is not possible to vary much on the markings in the middle (such as creating a continuous line). - It would be nice to have orange round tiles for the traffic lights as well. - And last but not least: There is not (yet) anything to build curved sections.
On another note: It would be good to just sell the old baseplates alongside this system for those that already have a large layout on baseplates. One way to make the old baseplates compatible with this is to just lay regular plates under the baseplates, so that the total height will equal two plates (four units).
Generally, I'm happy with the system, but imho improvement is necessary to make it a success in the long run, and I hope that cheaper road part packs will become available in due time.
