I played TS4 today around 20 games and overall it was fun but nothing I feel like I would ever buy, even it was only $9K like a Stern premium, it's just not for me. I think people who like it will like it but just not my cup of tea, I would rate it as one of the lesser JJP games kind of ok not worth $12K imo but some people will surely love it and that's all that matters.
As for the price, I understand it because it'll sell in this pinball market, I was thinking that the price is crazy to me but I am not buying it, someone who likes it will likely see fair value. I want a nice Tron myself and would pay a good deal, but if you look at the number of switches or coils and the the code or what you get in Tron, it's not really worth $8/9/10K but that's what a nice one would go for nowadays.
TLDR:
I got a chance to play TS4 today, there are 3 arcades within 5 miles of each other in Oviedo FL they have many nice pins LE versions of Elvira, JP, GB, TBL, CCR, AFM, Mando, etc.. they have quite a few pro versions and premiums but I think they buy to get the games as quick as possible. I mean they got GZ LE because that was the first out.
One arcade (Arcade Monsters) is an all day pass which was $24 (that's a bit pricy imo) but I support them for getting nice pins. Another (District Eat and Play) is $36 for the month which is much better deal and they have many more pins but they didn't have TS4 yet but they have every other JJP pin.
The third arcade has the most pins (The Pinball Lounge) but they are pay to play like $1/game or $2=3games.
That is just to set the table so to speak that ops can't buy these pins. There were two TS4 LEs within 3 miles of each other.
Here is what I found from playing like 20 games on TS4..
Pros:
TS4 looks nice and well built and solid feeling like every other JJP. The shots were nice the captive ball and ball lock felt nice and rewarding. The Kaboom ramp was very nice and probably the funnest shot on the game. The lights were nice especially the hot rails (or whatever they are called). The game is fun enough to play on location, I wouldn't regret putting $$ into it. I had been worried that the game or the code would be too easy but not to me, it seemed OK difficulty and enough code. I will play TS4 again to me this game is funner than GnR but I really don't click with GnR.
Cons:
The rules are just ok, the call outs are not my favorite ("hit the magenta and yellow shots" or "hit the cyan and green shots" or 'Hit Everything"). I guess they are instructuve tell me to hit the inner orbit or ramp but they don't make me laugh or have anything extra special for me. Maybe because I don't care for the theme being TS4. I am a huge fan of TS 1 and 2 and 3 was good too but TS4 is the weakest BY FAR and didn't use all the characters I really liked. The Theme is a minus as is they theme song played over and over and over. It also suffered form having every shot list up in different colors too much (to much for me) and I hated the digital pinball game. I think the iPad display is a waste everything in it could be on the big display and they virtual game is not for me. I don't like most video modes in pinball but this especially because it takes up a lot of real estate.
The game I played the inner loop feed to the small flipper was not feeding the flipper the ball was typically a quarter inch away from the flipper so it wasn't easy or consistent to make any shot with the small upper flipper. I am not holding that against the game but it didn't play 100% to me. Also don't know if this is typical but the slings seems to be oriented a bit off (to my eye the right sling was a bit more laid back) and the ball would volley back and forth a lot, not always but one time the ball volleyed back and forth like ten times, god I hope that's not normal because it's almost a game killer in my opinion of that's normal. I will again chalk that up to maybe the setup or this specific example.
