I think the gameplay would still be very fun even if you've never played a Tony Hawk game before. It's a unique combination of platforming and trick based racing/sports so if that appeals to you you'd probably really enjoy it. It feels great (it has been modernized somewhat) and it's the definition of easy to learn and hard to master. The only issue might be that the level designs might feel a bit small by modern standards, but these are some of the greatest video game levels ever made so if you are okay with that limitation then you'd still have fun. The game looks amazing too. Incredibly polished and if you didn't know that the levels were from a PS1 game you probably couldn't tell because of the level of detail that's been put into them even without altering the basic geometry. It's one of the best remakes ever from that perspective.
