Cheers for all the suggestions guys
MadMaxHellfire "keep playing those you already played."
yeah it is convenient to stick to what you know especially when it's the best the genre has to offer but you gotta broaden your horizon some time man. After all you can only feed Deidranna a lead meal so many times before even such a fun activity starts to get a bit stale. (I know, I know: sacrilege! And all that jizz :D)
rezaf Silent Storm: I did play silent storm quite some time ago and remember it to be rather fun. I haven't played Hammer & Sickle though, which seems to be similar and the unofficial successor. Is that one good too? Couldn't find it on neither GOG nor Steam sadly so might be hard to acquire.
Invisible Inc.: Can' really pin it down but somehow doesn't interest me that much even though it has good reviews and gameplay looks decent judging by viewing videos on Youtube.
Ebonsword Deathwatch: Thanks for the suggestion, I did play the game through the whole campaign on the starting difficulty and the game is indeed fun despite it's bite sized levels and grindy nature unless you give in to the micropayment stuff (or cheating like
Galdred mentioned). The curse of it's mobile origin I presume.
Taka-Haradin puolipeikko Door Kickers: another good suggestion, thanks. I picked it up a while back and played it for roughly eight hours and those were quality, entertaining eight hours. Yet it started to get quite repetitive after that point for me personally. Kinda like a "been there, done that" feeling you know?
ERYFKRAD 7,62: Looking at Screenshots from Steam I vaguely recall playing a pirated copy some time ago with a bad english translation and the feeling that I'm playing a poor man's attempt of recreating the Jagged Alliance style in real time. Almost like Back in Action only worse. But perhaps I didn't do it justice and ought to give it another go, proper this time around with the mentioned Blue Sun mod as well.
Mustawd Dayyālu Templar Battle Force: Funnily enough I deliberated getting the game a little while ago when I saw the first couple minutes of a gameplay video by TotalBiscuit of all people. But then I realized the creator of the game also did make Heroes of Steel, which is in and of itself a game with the right ideas and generally fun concept - which I picked up some time ago as part of a Bundle for 1$ - but was rather infuriated with by the little things like extremely long turn times even in small to medium sized fights, forced time eating turn based movement even with no enemies around etc. that are pretty much all things that make me hate unadapted ports from mobile games. And I was afraid the same issues might plague Templar Battle Force as well so I didn't pick it up or give it another thought. Since you two recommended it and I enjoyed the spirit - despite bad mechanics - of their first game, I will give it a go. Thank you.
laclongquan The only title from that trilogy I played was the first one, UFO: Aftermath. The art style evolution of the trilogy towards the comic style indicated to me more dumbed down, casualized gameplay so I never touched them. It's 3 against 1 in this Thread so far against those games so I won't bother with further investigation. But still thank you.
Modron Interesting list, naturally I played pretty much all of the RPGs from it plus Blood Bowl (which I found a little bit too random for my tastes by the way. Yes I know it's faithful to the tabletop but still). Chroma Squad is a little too far on the japanese scale of things for me personally. Same applied to Telepath Tactics at first glance when I initially found that game but I might have been wrong about that first impression. I always associated it with stuff like Final Fantasy Tactics or Fire Emblem.
Once again, thanks to everyone that replied and for all the suggestions. I will pick up
Hard West and
Templar Battle Force for the weekend and start from there. But feel free to keep the suggestions coming and this Thread going!
