It was a long time since I was so mixed on my feelings towards a game.
Also a bit difficult to review. Do you compare this to other cRPGs? If yes, then do you take the size of the studio into account? If no, then you just have to look at the end product, without considering the d20 ruleset implementation, the funding of the game, the studio size etc. otherwise you are a bit unfair.
I have no real idea how to feel about this game and reviewing it. I know I had a lot of fun, playing it in co-op with my girlfriend. To a point. Sometimes more, sometimes less fun.
I also think that I would never complete the base campaign if I was to play it alone.
I also really appreciate the great campaign editor and community content, but I never really spent much time on it. It is a big part of the game, but it is not "the game". Not sure how much should it be taken into account when reviewing, but it should be taken into account when appreciating the game.
Anyway, here are my thoughts in general, unordered manor:
Story (main campgain and DLCs) nothing to write home about in the main campaign. Just standard fantasy heroic shtick. You start of killing goblins end up saving the world from the big bad.
The story in the Lost Valley DLC is more compelling, as it is scaled down, although it lacks direction and possibly cuts of weirdly. Although it is generally better and more interesting. Could be better in terms of choosing factions and tying up loose ends by the end of it. The way they did it requires a lot of playthroughs to get it all, without that much diversity between them.
Combat Just like Baldurs Gate 3 (here I go comparing, team of 12, vs studio with like 5 locations and 600 people or something) the combat is the best part. While bg3 utilizes environment to make combat more like tabletop dnd, the cheaper Solasta focuses on lighting. It also has a great, clean, UI, in comparison to BG3, they did a much better job with it, however, the rules of combat are a bit different. Solasta is more pure DnD, while bg3 is more cRPG DnD, with a lot more stuff made easier, like magic items, backpack items usability etc. This results in a more strategic and tactical combat, while a more modern and bigger cRPG like bg3 has combat with far more options for cheese and weird stuff happening. They both are DnD, but they play out very differently. The biggest flaw of solasta combat is the speed. NPCs are super slow. The bigger fights get pretty tedious after a while.
Presentation The graphics are dated and simplistic. The VFX effects of spells look good, and along with concept are, in the loading screens etc, are the best part of the graphics. Otherwise, everyone looks like made out of playdough. Voice acting is... well... not professional. But that can be pretty funny. At least the maps are very clear, and navigating is pretty easy. This however makes for far more artifical maps than those from bg3, where maps are more like real locations, rather than locations made for rpg adventuring. This is passable due to the studio size and budget, but also hard to be overlooked, when many small studios put out great quality of art design and sound design. The game has some pretty decent tracks in terms of OST, but nothing really stays with you for long.
Other campaign editor is great. People have made great content with it, that can probably supress the main campaign in terms of story complexity etc. I have not used it a lot, but it is very clear, that its just good, very good.
RPG in terms of of mechanics it is a very faithful open ruleset implementation. So if you like DnD, you will like what they did. In terms of role playing, you are out of luck. No meaningful dialogue options, and the writting is often rather cheesy. Character characterization is hold back by graphics. Leveling and mechanical side are great and clear, mostly well explained. But sadly, often held back by technical state.
Technical state Game is buggy. A lot. Whole subclasses do not work (open hand monk). Whole areas would not work. Enemies would bug out mid combat requiring a complete combat restart. I tried reporting some bugs, but was left with no response or help. This is one of the biggest flaws, and ultimately left me and my gf abandoning the completion of the newest and last DLC due to inability to load into the next required area.
Ultimately we got around 100hours of playtime. 70-80 was really fun. The rest was sometimes a bit boring or troublesome.
If you gonna enjoy it, you probably need to be really into DnD combat or set your goals towards the custom, user content, either making it or playing.
