One thing we can all agree on... they are either the best thing in the game or the worst!
For me, honestly, these are the ONLY things I like about the game other than the S-Level license tests and Special events. What on EARTH were PD thinking, allowing you to enter an FGT in a race against 300hp saloons? The fact that the AI doesn't ramp up in car as you do is sheer laziness, IMO. And, I'm sorry to say, but it seems obvious that most players of the game are doing exactly that to progress as rapidly as possible. Me included! The temptation to do it the first time through, so you can get to drive all the cars is hard to resist..!
But, for long-term enjoyment of the game, having some events come in where you CAN'T over-muscle your way to the podium is a nice change, and indicative of where the game COULD go, if patched for more car equality. One thing I'd REALLY like to see in these Seasonal Events is the same stringent penalties for flagrant contact, so you can't bully your way to the front. These made the License and Special events SO much harder and more challenging. I'd like to see this added as perhaps a second 'tier' in the awards system (more XP and credits) to add yet another degree of challenge.
In the long run, after all the events are done in the main game, these events and online are going to be the ONLY thing left undone after you've had the game for maybe six months or so. Personally, I would like to see online turned into a LOT 'cleaner' racing by the simple means of making much of these new events as hard to pass as the S-License tests. If you LEARN to drive clean, if the game FORCES you to be clean as much as possible, then it's likely, once you get out online, that you are going to be 'clean' there, too. But at the moment, ONLY the License and Special events force that, and as soon as you hit A-Spec, barging your way around becomes allowable. This leads to players doing exactly the same thing online, because that's how they learned to play...
Me, I love the new events. I wish they were HARDER, but in the right way..!
Oh, and I REALLY wish there was some way to detune a car that you have upgraded. It's INSANE that, if you screw up modding the car for the event (or you already have the car, but you've boosted it too much or reduced it's weight too much) you have to buy a whole new car and start from scratch. IRL, you can take parts OFF of a car and replace them with the stock parts (you probably kept them). You can add weight back on to the car that you took out. You can replace the plastic windshield with the old glass one (unless you sold it - Hmmmm.... why don't I get any credits for the parts replaced in the game? Means I ought to still have the original lying around somewhere, shouldn't I?!), you can put back in the seats and padding you took out.
THIS is probably my main gripe about the Seasonal Events (and online, for that matter... got a GT-R 1hp too much for a Lobby, too f'ing bad! Can't detune it to join, can you?). 1hp too much, 1 lb overweight, got to buy a whole new car JUST for one event.
That's crazy...
