Im not exactly sure what to think about asking for games on another games forum - but since the market isn't too big I guess we all know how hard it is to actually find this stuff.
So, if no feelings are hurt, I might also name a few I personally came across and that are somewhat comparable to S4P - while leaving out those I don't consider good enough to waste my time on.
* Brothel King
* PyTFall
* Jack-o-nine-tails
In regards to the Strive for Power 2 demo... well... I finally found some time to look into it while still trying to work out some balancing changes for S4P 1 (I'm still on it - just haven't had the time to report back here - and there wasn't that much interest from the community to begin with. ^^)
I personally like the idea of shifting the focus of the second game more towards the management side and even put some crafting/farming components - but unfortunately I was able to spot multiple essential flaws within seconds of testing the demo - flaws that basically are migrated from S4P 1.
I'm fully aware that this is more or less a hobby project - and I'm aware that it's always dangerous to involve other people in such projects (been there - done that - has at least a 50% failure rate, I admit) but I HIGHLY suggest getting someone on board who has some understanding about proper UI/UX design. Doesn't have to be a professional of course - but there HAS to be someone willing to help from the modding community or similar.
I stick to my original assessment; Strive for Power (1 as 2) has quite the potential to become a really good GAME - not only something people fap to (pardon my French) - but it is most likely deemed to fail if it's done like the first one. It is doing some things quite well - but you REALLY have to get your gamemechanics (and their balance) and your UX in order!
I have to be honest here; if S4P 2 develops like I predict from what I've seen in the first game, I wouldn't recommend it to people - I would rather tell them to stick to the first one, because there currently ARE people modding the game to fix some of its major flaws. So please don't waste the potential and your time repeating the errors of the 'past' - it would be a shame!
