Well, okay, of course if you compare it to games like planet coaster, it's not even close to holding up, but...
Let's face it, this is a "discount bin" game.
The sort of game that isn't made by a studio, but rather by a person or two.
Now, that's not an excuse (Parkitect is made by 3 people, Rollercaoster tycoon 1 was the work of Chris Sawyer), but...
FOR A DISCOUNT BIN GAME it doesn't look too bad, honestly. I've certainly seen worse.
It doesn't look like it's completely lacking any effort, some love went into it and the coaster designer seems better than I've seen in similar games.
I mean, don't get me wrong, I'm not gonna pay money for this or anything, but, I dunno, if I was a kid and my dad picked this up for me at the store I'd give it a whirl. Might even enjoy it.
