It's not great. At first I was excited about the idea, despite the recycled art assets from Something Unlimited. After all, the original game from Gunsmoke had a lot of issues with pacing, grinding, and so forth. Having a reworked version with different gameplay could be really enjoyable.
But that's not what we got. What we get is is basically the same, just... less of it. So we still need to wait for the days to pass in order for the Glamour Slam to make enough money for us to buy upgrades, and we still need to upgrade the legions/glamor slam/devices to get new things. The only thing that is improved is that we don't need to go through the process of setting the schedule for the dancers, or fiddling with the device upgrade menu. It seems like just an incremental step, when the best thing should have been to just do away with all the money and upgrading mechanics to begin with, what even is the point.
The same thing goes for the progression with the girls. The original SU has a lot of grinding in that you need to repeatedly visit each girl to unlock slightly more content, starting with dancing and then stripping and then more explicit acts. It can get tedious and repetitive.
Now, this would be the main draw, the big thing that would place Something Trainer over Something Unlimited. If the whole point would be to make this more of a focused trainer game, the training aspect need to be more robust, more interesting. Maybe some more stats, breaking down the resistance of the girls, definitely more dialogue and reactions. And we do get a bit of that, to be sure, there's a few dialogue options, asking characters opinions of other characters. But it needs expanding. I would say that rather than going for LOTS of chars with shallow interactions, like the way SU does, it would be better if there's only a few characters but lots of in depth interactions. And not all of it needs to be sex, given we're only working with a limited supply of art.
The writing and the UI are not as good as in SU. One of the big disadvantages of SU is having to click around endlessly to move from room to room, and to advance to the next day. Something Trainer does not fix this at all.
For instance, you're given the option to have some conversations with Batgirl, ask her opinions on the villains she fights. This is an interesting addition to the game that was not something in SU. However, to access this dialogue menu we need to first click into the cells where Batgirl is, click walkies to take her to the club, then click champagne room, then click "spend time with her" and only then can you reach this dialogue menu! How ridiculous is that?
With the writing, there are a few grammatical errors, in particular with punctuation and capitalization. There's also a lot of parts that lack detail. For instance, in SU we get several lines of descriptions when characters strip or dance in their cells. Some more than others, and they will start to repeat, but they're usually exciting on the first go.
In this trainer, I've come across several dance/strip scenes right near the start where the description is basically just one line of "Girl takes off clothes." It's not really a good mood-setter. I know that the art is limited to what is provided us in the original SU, but writing is one of the key places to differentiate these two games. Having some better written smut would be a big boon.
Credit to where it is due, I really do like the things this trainer does that are not in the original at all. In the previously mentioned example of Lex talking to Batgirl, I thought Lex's characterization as pretty on point for arguing about how he does very similar things as Batman, and his whole argument against Superman being too dangerous. Batgirl on the other hand though feels OOC, a bit too weak-willed, it would've been better with a more lengthy period break down/discipline period.
All in all, I appreciate the ambition but a lot more work needs to go into this to be anything more than just a mediocre cover-band version of SU.
